@Donderpants.... What?? Did he delete his post?? And this quote "women are almost certainly on average smarter than men." would be sexist too... Its funny how you can say you are fighting for equality or say you support it without actually doing so. You should argue that intelligence is decided on an individual basis not a gender basis.
I'm male myself, but in the collection of people I've met in my life, the boys are on average pretty stupid in comparison to the girls. And I did say on average. Some individual males are smarter than most females, and some individual females are smarter than most males. But if you go for a mean average, from personal experience I would guess that the average girl would score a bit higher than the average boy. Perhaps it was just the school I met most of those in was better at teaching girls than teaching boys, but if not, girls are certainly on average smarter than boys. Not all boys, but on average.
