The Belmont Club Looks at Hate Speech on Religion: "Blackadder star Rowan Atkinson has launched a comedians' campaign against a government bill to outlaw inciting religious hatred. ... Mr Atkinson told a meeting at the House of Commons on Monday night there are 'quite a few sketches' he has performed which would come into conflict with the proposed law.

He added: 'To criticise a person for their race is manifestly irrational and ridiculous but to criticise their religion, that is a right. That is a freedom. The freedom to criticise ideas, any ideas - even if they are sincerely held beliefs - is one of the fundamental freedoms of society.'"

I think making fun of what people believe is often offensive, in poor taste, and even rude. But should be legal.
Prolly even making fun of their race, but that's a bit worse. What about their "sexual orientation."
