I'm not sure I'm that happy with the way gay people are referred to in that link, it seems to have been written by someone with quite dated attitudes, i.e. that a lot of gay people hate themselves.
I found this part very strange:
Not all (or even most) members of the gay community are killers. Some serial killers have been gay men. The reason behind their crimes may be, as proposed by Maghan and Sagarin the simple fact that they are taking out their rage at being gay on their victims. Or another way to explain the crime is that the victim because a symbolic victim, the victim becomes a symbol of what the offender hates the most...himself.
As a gay man myself, that sounds like something that might have been written a few decades ago.
I will have a bit more of a look at the site tho.
