From what I understand the principle element of Christ teachings was two things, "Love your neighbor as yourself", and "Do unto others as you would have them do unto you". Im pretty sure it goes on to say, "do these things and you will keep all of my fathers teachings", but Im not going to look it up, so I can give ya a passage, because I dont believe in nit-picking spirituality. You do that, and you end up with a religion, and ALL religions suck.
Anyway, churches condoning Homosexuality as fine are just doing unto others as they would have things be done to them. They wouldnt want to have people tell them they couldnt love who ever they wanted, so theyre like, "Well Christ taught this was right so...." Those people are TRUE christians. The ->-bleeped-<-ers who spread hate about Jews and loved Nazis ect ect, they werent christian because they werent "loving their neighbors", and they wouldnt have enjoyed gas showers. Jee, its not rocket science to figure out that the guys preaching hate are more akin to the Nazi lovers than the people of true faith accepting people who love Christ, but happen to love the same sex as well.
