If I was to pick *just* one thing, I'd say perverts have ruined manhood.
Internet culture has twisted the once noble figure of the man into a pathetic, whiny, pallid, unhealthy, greasy, unshaven, awkward, irritating freak that constantly runs after the goddess like figure of "The GF" to ABSOLUTELY no avail.
The "Wanker culture" - wherein most males accept and broadcast that they're pathetic for the sake of cheap laughs, display a crippling fear of male (and only male) homosexuals, and "grudgingly" admit that poor quality, uncreative pornography is the only sexual attention they get - is a pox and a plague that only makes men less appealing to me, and does a fairly good job of not only alienating the women they want more than life itself, but promoting sexism AGAINST men.
Basically, it's very hard to see Dohvakin (Lusty sigh) from behind the smokescreen of perverts and porn.
