If he's referring to people who beat up, maim, or murder gays, it's just cruelty, not mental illness. And there's a remedy for that--stern jail sentences.
Yeah, agreed. The key point about, for example, the Matthew Shephard murder was that it was committed by murderers. Who were also homosexual. But both those significant points were outright refused in any discussion about Shephard's sad demise.
Murderers murder. The only "hate" element in that particular case (Shephard) was that it was murder that killed Matthew Shephard. Although the murderer was also homosexual (at least the one of the two).
Somehow, that's reduced to the problem of generalized "people" "hating" "homosexuals" but the truth of it was that Shephard, a homosexual, was killed by another homosexual. But it was murder that took his life, and a murderer who took it.
It's still, however, talked up to represent the result by social "homophobia" about homosexuality. Which seems to be the ultimate insult to Shephard himself, in my view.
