Because, when you like it or not, religion is a protected category just like sexual orientation is. Members of protected categories are allowed freedoms which are not allowed outside those categories, one of these being the citation of scripture. Rest assured that there are plenty of people who think the same about the displays of obscenity which pride parades have turned into but since these are also part of a protected category they can't do anything about it either.
The solution to these problems is to do away with protected categories altogether and just apply the law to all in an equal fashion - I'm all for it.

That's not really how it works in the US. Except for age, every protected category applies to everyone. Even if your answer is "none", that's protected as much as any other answer.
Plus I still don't see the problem. Surely protected categories are there to protect people, not give them cover to do otherwise illegal things.
People can discuss mein kampf without getting to hate speech, the same should be true of a religious text. And if that is impossible maybe that religion shouldn't have special protections.
