I don't think that christianity is innerently against lgbt people. It depends on who you ask.
Easy example: both my grandma and her sister are catholics. My grandma says that god says to love people, so she doesn't care if I like boys or girls as long as I'm happy, because your sexual identity doesn't make you a bad person. Her sister thinks that gay people are kinda disgusting/have some mental issue/have had bad influences or not good parents, or whatever, I won't ask her.
