The point of alcohol is to lower inhibitions. More Bad Things happen per person hour under intoxication than sober, by design of the substance.
Recently, I've had the thought that feminists and hardline social conservatives ought to find common ground around the alcohol/party culture. Feminists should also ask themselves - for whom and by whom was this culture made in the first place? Does it work in women's favor? It's unrealistic to think that we can reduce sexual aggression while leaving this culture the same.
I wonder what percent of sexual assault occurs while both parties are sober?
