encouraging co-ed children's sports to the point of banning gender segregation - and using brown v board as a model - would be good for both young girls and young boys, as it would teach them to see each other as equals rather than place each other in a fraudulent hierarchy. i think it's healthy and positive and progressive to place boys and girls in situations where they compete against each other and both win and lose and also where they cooperate with each other in ways that aren't gender segregated. i remember the boys v girls soccer games when i was a kid and that should not be allowed, by law. integration should be enforced by federal law. segregation should be prohibited by federal law.

it teaches boys that it's not shameful to lose against a girl and it teaches girls that they can beat the boys if they try. both of these things undo the remnant christian cultural programming which is proving very stubborn and hard to abolish. 

it also teaches both boys and girls to work together in ways that transcend gender segregation, by building alliances with the opposite gender to defeat members of their own gender. this undoes the damaging gender war mentality constantly enforced by the culture and media.

that's an ideal, it's equality, and recent regressive policies are showing that it's going to be necessary to enforce that kind of equality through aggressive brown v board style mixing because the culture is too ignorant and too stupid to get there on it's own.
