What they don’t hint at....is lesbian suicides...which I would suspect are pretty low (if they don’t mention it).
Why do you say that? Women are actually more likely to attempt suicide than men. Granted, men are more likely than women to successfully commit suicide.
So a disproportionate amount of gay men commit suicide. If stats are consistent across the population (big if) then it would make sense for lesbians to have a similarly disproportionate amount of suicide attempts.
Either way, what is your ooint in saying that lesbian suicide rates are lower?
