Boys and girls have different brains!
Wait! Really! No shit. We are totally serious here.
Now, of course, we await the thunderous cascade of contrition and apologia directed towards Larry Summers, president of Harvard University, who said much the same thing earlier this year; he was nearly forced to resign, after the ensuing idiotic brouhaha by the supposed "intellectuals" inhabiting that institution.
What they actually are is "brainwashed".
Any parent, of course, could tell you that boys and girls are, generally speaking, just different. And have been different for oh, let's see, add the 4, carry the 1 ..... eternity. Freaking forever.
Proving, yet again, that some things are so stupid, only an intellectual would believe them.
