I'm not sure that can be correct. If it is correct, then a group of nutters (eg, the BNP) could have a religious group which could write whatever you want, which you could then preach. It is not ok to say that sharia people should live by sharia law if that law compels you to kill people, as you are encouraging people to commit crime. Just because it's religious text, does not make it a hate crime.I think maybe you mis understood what i was getting at.
Choudary can preach his version of the Koran till the cows come home, he can preach that gays can be killed according to sharia, he can preach women can be stoned for being raped,he can preach people can be punished for all sorts of "crimes" we think are not even crimes in the first place.This is not hate speech even though we hate it, it is simply promoting genuine religious text.
What he says is not against the law, everything he preaches is in the koran and therefore not illegal
