MY suicidality has never had anything to do with my gender, as I perceive it, although the rate of homelessness and succesful suicide attempts among men compared with women is interesting.
I think biology, compounded by the Cultural Hegemony of "the Left", make men less appealing to be receptacles of pity and good disposition, so it's probably a bit easier to end up alone or dispossed if you're a man.
Obviously, in this trade off men get rid of rape, sexual harassment, trafficking, pregnancy and such. All in all it seems like we are in a worse position nowadays but I feel like personal circumstances matter much more in how one becomes despondent or suicidal.
