Many foolish, and even abominable things have been and are done in the name of that possibly mythological figure, Jesus.

Of course you suspect that. You seem just like all other non-religious (or at least non-christian) people who think they know what they are talking about when they discuss matters of Christianity. But unfortunately if you read the Bible it is not the all inclusive religion that you folks make it out to be. In fact we are told to send a person away if they are unwilling to repent of their sins, of which homosexuality is unquestionably one, and any argument that it is not comes from ignorance about God and sin in general.
But don't worry. You guys will "win" in the short run. We know that because the Bible says you will. Unfortunately it's the long run that really matters.
