yeah, those moms need to realize that male dancewear is totally different than the stuff girls wear, so wearing tights isn't going to make you any less of a guy (heck, if you are well built, it shows off your masculinity).
Anyways, yes i have heard of girls actually playing football in high school. Ok, not as quarterback or linebacker, but i've heard of girls who are the team's kicker. I've actually heard of girls getting inxvolved in wrestling too (i wonder if that's a bit much though!) However, most sports are not coed though, and i'm fairly ok with it (but not totally). [/i]
