Mood (Affective) Disorder Homophobes
Depressive homophobes bash gays and lesbians in order to relieve their personal feelings of worthlessness, which may appear when (1) depressive homophobes put themselves and their achievements down unnecessarily, as when a straight blue-collar construction worker feels inherently inferior because he is not a white-collar semiprofessional; or a white-collar semiprofessional feels inherently inferior because she is not a "real" professional. Or they may appear when (2) depressive homophobes put themselves down rationally, having recognized the truth: that they are troubled people who have in fact achieved little in life.
A large group of these depressive homophobes feels personally worthless in comparison to gays and lesbians because they envy them, and they envy them because they think they have it all. They handle the belief that gays and lesbians have it all by putting them down to even the score. They bash them for the same reason some fans bash their sports heroes when they lose. Manifestly they are booing them for being losers. But secretly they are just using the loss as an opportunity to express a simmering angry jealousy at the players for playing while they, the fans, remain on the sidelines.
One straight man stared bullets at gay men who were in groups obviously enjoying each other's company. He envied their being together because their being together called his own loneliness to mind. When he railed against "faggots" he was in fact condemning them for having the fun he felt he could never have. The same man called all gays and lesbians elitists, condemning them in a way that sounded suspiciously like a compliment.
