I just don't get why some people are so vile about gays. What is wrong with having a relationship with someone of the same sex?
Short version?
computer God says no.
Don't look for a deeper explanation than that. There isn't one. That's all it comes down to with these types, in the end. God says this, God says that, God says the other, yadda yadda yadda. That's about it, really. Say 'God says it' and for those who respect bullshit, that's the end of the conversation.
Normal, sane people raise pertinent objections to this, but because even today we labour in societies where respect for irrationality is considered a liberal, humane virtue; the irrational and illiberal and even insane still have the right to say their say.
We have a moral duty with these, I suppose. I will defend that to the last ditch. Reluctantly, as I despise superstition and irrationalism. But for me, the moral duty comes in listening to, not agreeing with. I am sorry for this, as I don't like what is commonly called religion which in practice means that I don't like what are commonly called religious people. I think that in a great many cases their pretence at what we call thinking is clownish and their conclusions ridiculously, utterly absurd to the nth degree, and often at best patronising and at worst downright poisonous whenever it comes to things like being gay. But there it is, and so be it.
Some use the Bible as an excuse for their nastiness. If god, assuming it exists, is so against homosexual relationships why isn't it one of the THOU SHALT NOTS?
Well ... yes.
There's the old gag about there being hundreds if not thousands of commandments and prohibitions in the OT against heterosexuals and relatively speaking a handful against homosexuals, suggesting that there's nothing wrong with heterosexuals except that they obviously need more supervision
