Most religions respect the truth and forbid lying. However Islam is different.
Allah is 'the best of deceivers' (Koran 3.54), and since the highest goal of Islamic ethics is to spread Islam by any means whatsoever, it is hardly surprising that lying and deceit should be quite acceptable if carried out for the benefit of Islam.
This 'Holy Lying' is known as taqiyya (sometimes spelled taqiya or taquiya) - This may take many forms, including outright lies, feigned moderation, and condemnation of terrorist attacks to the Infidel while rejoicing with fellow Muslims.
Here are some of the ploys, arguments, logical fallacies and diversionary tactics used by taqiyya tacticians:
 Taqiyya about taqiyya.
Of course taqiyya won't work once the infidels realise they're being duped, so Muslims deny that taqiyya exists, or that it is used to deceive infidels. 'There is no such thing as Taqiya' or 'Taqiyya is something I never heard of and I had to go and look it up' or "Taqiyya is only practised by Sunnis/Shi'ites, we Shi'ites/Sunnis always tell the truth". See here and here for refutations. Also Denying the Denial: Taqiyya About Taqiyya; Lying About Lying
 Playing the race card and guilt by association.
An accusation of racism is such a trump card that Jihadists will play it whenever they can. Despite Islam not being a race, any criticism of Islam immediately gets the knee-jerk retaliation of 'racism'.
For example; 'You are expressing the same views about Islam as racists, therefore you are a racist.' This is similar logic to to 'Communists believe two and two make four. You believe two and two make four. Therefore you are a Communist'.
 Godwin's Law
- a special (and inevitable) version of guilt by association with racism used in online discussions, whereby the first person to invoke Hitler or the Nazis wins the argument. The 'logic' is something like:
CRITICISM OF ISLAM = RACISM = NAZISM
Therefore, if you criticise Islam you are a Nazi.
 Circular reasoning
'The Koran says it is the word of God. So whatever it says must be true. Therefore it is true that the Koran is the word of God because it says so'
 The infidels' quotes from the Koran are always taken out of context.
For example 'Kill the unbelievers wherever you find them' is taken out of context, and really means 'Kill the unbelievers wherever you find them setting fire to your house' - or something similar.
 Infidels can't understand the original Arabic of the Koran.
So 'Kill the unbelievers wherever you find them' is actually a Medieval Arabic expression meaning 'Help old ladies across busy streets and remember to feed the birds in winter'.
 Tu Quoque (you also).
'We blow people up/ behead them but you do the same,' - Normally used in attempts to refute arguments that Islam is intrinsically violent. Often refers back to the Crusades, Inquisition etc. Also 'There are equally nasty bits in the Bible'. Yes, there are violent episodes in the Bible, but the Bible is descriptive of battles and massacres long ago, whereas the Koran is prescriptive of battles and massacres yet to come.
 'Abrahamic/monotheistic faith' false kin argument.
This scam usually take the form of 'Islam is just a further development of Christianity, a brother Abrahamic/ monotheist faith.'
Of course it isn't! Islam is a travesty and perversion of Christianity in many respects, and Jesus would probably have advised the pedophile Mohammed to tie a millstone round his neck and jump into the sea. (Mark 9:42). In Islam stoning of women is still a major spectator sport, whereas Jesus forbade it (John 8:7). Human sacrifice is an abomination in Judaism and Christianity, but is encouraged in Islam.
Another Satanic aspect of Islam is that it deliberately destroys the conscience of its followers.

 Quoting abrogated verses from the Koran in order to appear moderate.
A favorite one is 'Let there be no compulsion in religion'. This verse and many like it are actually null and void and disregarded by all Muslims (though not by gullible infidels). They are peaceful Meccan verses which are completely cancelled by later and much more violent Medinan verses.
 'You owe us a debt of gratitude because Islam is the basis of Western civilisation'.
This sort of statement is usually backed up by revisionist arguments that Muslims invented everything and were responsible for the Renaissance (Sheikh Speare was a Muslim playwright etc).
In some ways this is a rather pathetic quest for significance. Muslim culture has been moribund for the past 600 years, whereas the West has forged ahead. Muslims now want a stake in the success story by claiming they were somehow responsible for the West's development.
 'A third of the world's population believe in Islam, so it deserves respect.'
- But not so long ago a third of the world's population believed the earth was flat. Numbers don't mean anything, especially when the Islamic population is the most backward and illiterate on earth. Muslims are very keen on 'respect', but someone should tell them that respect needs to be earned.
 'We are victims of Islamophobia'.
Muslims are always playing the victim, if not of racism then of the even more heinous thought-crime of ISLAMOPHOBIA. Of course there is no such thing as Islamophobia, since a phobia is an irrational fear, whereas fear of Islam as a clear and present danger is a totally rational reaction from any infidel.
...and, let's make it a baker's dozen...
 Sufis are non-violent
This is an example of the Good Cop/Bad Cop routine. Sufis portray themselves as being a kind of Buddhist version of Islam: peaceful, mystical and generally fluffy and New Age. Well-meaning Westerners are attracted by Sufis in the hope that they have finally found examples of the elusive Moderate Muslims.
Unfortunately, this is clutching at straws. Sufis are just as violent and supremacist as the rest of them. See links under Sufis at Everything you need to know about Islam.
A particularly good example of the Sufi Good Cop/Bad Cop contrick was the Ground Zero Victory Mosque, where the 'peaceful' Sufis deceived the more gullible New Yorkers until they were exposed as normal Muslims.
Moral Equivalence as Self-administered Taqiyya
Those infidels who use the 'moral equivalence argument' to compare Islam with other religions need to examine their own subconscious psychological motives. They are not only attempting to delude others, but are in deep denial and trying to delude themselves. They are administering self-generated taqiyya as a tranquilizer to blot out reality.
The conscious part of the moral equivalence argument takes the form "Christians and Jews have committed atrocities such as the McVeigh, Breivik and King David Hotel bombings, so Christianity and Judaism are just the same as Islam. Therefore Islam poses no special threat."
The fallacies are obvious: Christian and Jewish acts of terrorism are rare and infrequent; they are rejected by the majority of followers of the religions, go against the core teachings of the religions, and are committed by a few isolated loonies. In contrast, Islamic acts of terrorism are commonplace, are encouraged by the Koran and are supported, if not actually carried out, by a substantial proportion of Muslims.
The unconscious and self-deluding part of the moral equivalence argument is the refusal to face the fact that Islam is an intrisically violent totalitarian ideology that has infiltrated our civilization, and is bent on our conversion, subjugation or elimination. To acknowlege this would be deeply disturbing and well outside the comfort zone of most people (remember the popular enthusiasm for appeasement of Hitler and 'Peace in Our Time'?) . So we reassure ourselves, by the moral equivalence argument, that Islam is just like other religions.
It's far easier to stay in denial and regard Islam as being no more a threat to our lives and culture than the Quakers or Lubavitcher Hasidim. That way we don't have to worry about the looming global clash of civizations, or think about the unpleasant courses of action that may be necessary to reduce the threat.
Moral equivalence is moral cowardice.
Don't Mention the Jihad!
"One dominant theme during Ramadan in the Arab world is the discussion, in the media and in religious circles, of the commandment of jihad and the obligation therein to wage war against the infidels. It then focuses on two recent op-eds, written by Arab-Muslims, that discuss the need to tone down Muslim talk of offensive jihad.
One writer, Khaled Al-Ghanami, states that the “wiser” supporters of offensive jihad believe that Muslims “must sit and wait until the era of our strength returns.” In the meantime, according to these Muslims, “there is nothing shameful about taqiyya [deception] until the time is ripe.” Al-Ghanami bemoans the fact that such Muslims operate naively “on the assumption that the world doesn’t read, doesn’t monitor … and is not paying attention to the calls for killing, tyranny, and aggression that we are spreading.”
Similarly, Abdallah Al-Naggar writes: “Today, the Muslims’ circumstances are different [i.e., they are weak], and talk of this aspect [of jihad] requires a smart approach, one that stresses the aspect of self defense, instead of aggression and onslaught,” since discussing offensive jihad “arouses the enmity of people”; thus, “there is a need for wisdom [i.e., kitman] in our impassioned discussions of war and battles.”
These writers are insightful enough to understand that Islam’s imperative for Muslims to wage offensive jihad is the one insurmountable obstacle for peace between Muslims and non-Muslims. Best not to keep reminding the infidel world, then. More at http://pajamasmedia.com/blog/offensive-jihad-the-one-incontrovertible-problem-with-islam/?singlepage=true
The bottom line message is
Don't trust them and don't believe a word they say!
