I always hate these threads, the most uncontroversial opinions (on the internet) are always pushed to the top. That said, my most controversial opinion is probably that LGBT people should be accepted in Christianity. To the vast majority of my fellow Christians this is 'against God's will' in some way or another and to any non-believers the idea of God is ridiculous.
After years of religious schooling, this is one of the things that really makes me seethe. Not only is there no standing for the rejection of LGBT in Christianity, judgment of others is completely "against God's will." Casting judgment of others or professing to know God's will is like saying you are God (which is considered blasphemy, the greatest sin you can commit as a Christian). The New Testament is nothing but the Christian God saying leave the judgment up to me, y'all just need to love each other and play nice. Being hateful towards any group or person is explicitly anti-Christian.
I guess I'm pretty fortunate because most of the Christians I know are prettying accepting of the LGBT community. It's interesting though how those Christians that are opposed to homosexuality quote Leviticus and justify their beliefs with it. Leviticus also bans the consumption of shellfish, yet I don't see any movement vehemently opposed to that. I think we'll see a shift within most churches soon. Many leaders of the church recognize that anti-LGBT beliefs tend to drive away more members than it keeps, especially among younger generations. I think we were raised to be more tolerant of sexuality than the generations that preceded us, and as we "take over", how everybody views and treats the LGBT community will change.
