Hey guys, maybe consider the case of the people who this affects: the girl who doesn't have a father to bring to the dance, and wishes to bring her mother instead. Or the boy who would rather go to the dance than play baseball. Or the girl who wants to play baseball with her mom or dad.

The problem is that the status quo excludes those kids. No one is trying to ban dances or baseball games, they're simply trying to ban making them exclusive. You might benefit from asking yourself why you support such an exclusive environment for kids.
