The only thing I can add is that if I were a religious fundamentalist and went around posting things like that through letterboxes, I would have the balls to stand up for my convictions and not squirm my way out of it. One of the defendents said that he had nothing against gays, and that one of his lecturer's was gay, "and he's my favourite lecturer".
Peter Tatchell recently said (and I agree) that we should stop persecutions of any one who preaches that homosexuality is a sin.
Fair play - to them, it IS a sin, and they should be allowed (as well as Christians, Jews, Hindus etc), to preach that.
However, there has to be a line drawn - you cannot call for the murder of anyone, even if your religion explicitly condones it.
According to the Bible, women who commit adultery should be stoned. That may be the case, but if I stood on the corner of our high street calling for the murder of women who'd committed that particular sin, it would be right for me to be pulled up for it.
...because it's incitement to murder.
