Why is it? Playing devil's advocate(or I guess God's advocate), if homosexual relations are sinful, should that be a reason to hate gay people?
Actually, I'm not sure what you mean by that.
What if the 'sinner' is in this case completely morally messed up? I don't have to love someone like that. It's fairly bad logic and just another way to treat a minority as 2nd-class citizens.
