So men's weakness is a predisposition towards violence and irrational behavior, and women's weakness is... men's predisposition towards violence and irrational behavior.
samfoo never made the claim that men and women had the same weaknesses. He was simply stating that men are also disadvantaged because of their own nature. If you're a woman and are able to avoid violent or bigoted men, or are able to defend yourself against them, then you are not disadvantaged as someone who can't defend against those men. And to ricefield's claim that girls are no longer "disadvantaged.", there is some truth to that just looking at what's happened over the last century.
