Sorry, Change mine question

From the the presentation from Friday, it gave me some ideas about how boys were treading girls. I thought for a while that boys were naturally stronger than girls but that doesn't mean anything. What I mean is that: is a male can do hand work better than females, then from some scientists lab research that females were better in languages than most of the males. From this point, what I can think of is that we should only look at the better side of another's(ex. strength etc.)
