I've not seen any - most of the posts from homosexuals or pro-homosexuals have tended to be rather civil, on the whole. Sure, there's been a bit of snappiness and irritability sometimes - with the conversations normally ending up on a repeating cycle within a few posts of any given thread starting, that's pretty understandable; but that tends to apply to all sides of the argument, and factoring it into the equation, it tends to be those on the anti-homosexual side of the fence who are more inclined to...well, it varies from lack of understanding, through unkindness and unpleasantness, up to what seems to - very occasionally - veer into sheer hostility and hatred, or at least something that comes across as such.
I suspect that part of the problem is that for those on the anti-homosexual side of the debate, it's very much an "us and them" scenario, whereas most of those on the pro-homosexual side are both Christian and homosexual - or bisexual, or occasionally heterosexual, but most importantly Christian, and therefore for them to post in a manner that's hateful towards Christians would be a bit...well, odd, IMO.
