"On the other hand, that's a tyrannical society which forcibly boosts girls and women at the expense of boys and men."
First of all, as others have pointed out, equality does not mean forcing everyone to have equal abilities. Equality means not pre-judging anyone's abilities based on irrelevant characteristics like sex or race. Second of all, arguments like yours always clue me off that the person making the argument is operating under the default assumption that boys and men are better than women and girls in general and that assuming that they just might be equal for any given task until proven otherwise is tyranny. Let me guess: MRA?
