Wait... do you think females should be fixing the 'rape problem'?
Well yes. Men aren't going to fix this alone. As I said it's not reasonable to expect all men to be out like Batman watching everywhere just in case a woman decides she wants to go on a night out, get blind drunk them walk home alone through an empty park with little to no lighting up.
Prevention I'd say in this case is far better then a cure (mostly because the only cure is brain chips for all men or literally kill all of us men just to make sure or that crackpot feminist plan of killing 80% of the male population to keep the remaining 20 as breeding stock or something).
Prevention:
Push the idea of looking out for one another in your friend group
Push the idea of not getting blind drunk unless you can really trust the friends you're out with to look after you.
Push the idea of testing to make sure drinks aren't spiked and push for the use of anti spiking stoppers etc
Push having a plan, if you get split up you plan to meet somewhere.
Push the idea of carrying rape alarms and or rape inc
Push the idea of not walking home alone through unlit or dangerous areas
Push the idea of self defence classes so if anyone tries that women can break their attackers arm or at least do some damage to put them off.
Stopping the cycle:
Push the idea of going to the police if something happens (something some feminist groups etc were saying not to do before, see Suey Park), none of this "Oh but he seems like a good guy and helps the progressive cause so much and maybe I shouldn't come forward" stuff either. This helps attackers get put away so they can't keep reoffending.
