Why does it seem most people, mainly conservatives, against Trans people? Unless I am wrong I never heard of one shooting up a school church or whatever. The ones I have met have been pretty cool.
"Religion" is too broad a term. Conservatives like to call what they practice Christianity, although it would have appalled Christ. They also like to represent themselves as the mainstream of Christianity, but they are very much in the minority. They just get on the news more often.
