(1) Once you're in either organization you can't leave voluntarily (apostasy). The only way out is death.

The difference between predatory cults such as Islam and real religions, is that a true religion attempts to bring out the best in people, whereas a predatory cult does the opposite.
Muslims inhabit a different moral universe from the rest of us, where good is evil and evil is good, if it serves the purposes of Islam.
While other religions teach goodwill to mankind, Islam teaches hostility to all non-members of the cult.
Jesus, in the parable of the Good Samaritan, taught his followers to help all people in need, irrespective of their religion. Jews are commanded to be a light unto the nations. The Buddha taught compassion for all suffering beings.
But in Islam, charity applies only to fellow Muslims, and in fact many Islamic charities are money-launderers for jihad.There is no Golden Rule in Islam. There is no place for conscience in Islam. Peel away the thin veneer of religiosity, and all you find is vicious, primitive, predatory tribalism.
Once you remove Islam's 'religious' disguise, you are left with nothing more than a thuggish, insidious, murderous, seditious, tribal, predatory criminal conspiracy. There is no place for Islam in Britain or anywhere else in the West. Its entire ethos is totally opposed to civilized society.
