Ok, let's just follow a normal girl's life.
Infantry is all normal... so we'll ignore the first few years.
Starting in elementary school, you might have this one "really smart" girl in class. Big deal, that's early in life... they'll grow up to be stupid sluts byt the time they hit 13 and fail all their classes.
Middle school, they get their virginity taken and stop caring about anything other than sex. While males on the other hand absorb education better with a sex life (some without, who cares, still smarter than a virgin bitch, who's lying about it anyway).
High School... The girl applies to her local zone school because she can't make it into any other higher tier school because of her bad grades in middle school. But notice the males are the opposite, then there are some idiot males, but their lives end there with a several thousand dollar credit card debt after buying millions of gil and giving it to artificial girls online to marry then ;p.
Now college, take all of the "who's who" colleges in the US, or hell even around the world, who has the overall advantage in population? Male or female? duh...
Moving on to careers. Males get paid more... higher GPAs, better schooling, holding most of the richest positions on earth today. While females deliver my fedex packages ontime everytime and pour me coffee at dunkin donuts, satisfy the disgusting rich men or the dirt down poor men at strip clubs... yeah. I hope you get the point.
BTW: My gf is smarter than I am.
