It is truly depressing. Jesus spoke in Matthew 22:36 through verse 40, very clearly. Unfortunately, some people don't agree with each other. In Ephesians, Paul wrote about changing from the old man to the new man. But some Christians don't follow that. How are sinners to be led to Christ, if some people who call themselves Christian don't even have it down? I'm not going to throw the first stone, because I've been a hypocrite myself, but even if homosexuals sin against God, doesn't mean our responsibility to love them like Christ does changes. Don't get me wrong, I don't believe homosexuality is right, it is an ABOMINATION to God, and should be to us as well.
However, they need a reason to change. As well as a desire to leave their past behind.
Like what Jesus told the disciples before he sent them abroad, if that city does not accept you, then shake off the dust and move on. It would be worse than Sodom and Gomorrah for them.
