We used to beat up kids when I was growing up who played basketball, as we considered it to be a girl's game (still is). One of my childhood pals used to be on the receiving end of that periodically; he went on to be a pretty good D1 collegiate player and played in the NBA as well. However, given the fact he was a basketball player, we all considered him to be a fairy.
My wife played basketball in highschool and college, but she is a girl, so it was okay.
