Discrimination ok, if based on religion? what else then?

A while ago near here, during a discussion involving inclusive curriculum topics, a school board official stated, "Religious belief does not trump human rights." I agree entirely.If a religion runs into trouble because it preaches hatred, so much the worse for the religion; its practitioners should be subject to whatever penalities are usual.

How far should one go in allowing religions special exemptions on human rights? We already see discrimination based on gender and this thread mentions institutionalized homophobia. If a church believed in cannibalism, would that be okay? (After all, the catholic church claims this already!) How about human sacrifice?Should societies allow attacks on their deeply-held values just because someone has religious notions? Should religious belief trump human rights?
