I think many people in the west feel that they are racist or bigoted for criticizing a religion or culture that's not their own. And they don't wanna be associated in anyway have zero understanding of the Islam and think all Muslims are terrorists. (I think the same thing happens with criticizing Judaism and being associated with "Nazism") I think those people feel the have more grounds to criticize Christianity because almost all of western culture intertwined with it (and still is) and has overall not been massively persecuted here since Roman times (I believe).

Really, the Bible, Qu'ran, and Hadiths clearly state homosexuality is wrong. It's there plain as day. Personally I don't know how you can be gay and still prescribe to any Abrahmic religion. All books have the directness to maximizie homosexuality as a major issue yet both are self-contradictory enough minimize homosexuality to a minor issue. You can justify anything, even two contradictory sides within one book.
