KiMi --
I'm not surprised that players would say unkind things to you during a game -- afterall, you are doing your best to beat them, and it sounds like you frequently do so. I've been on enough sidelines and talked with enough players to know that vulgar comments of all sorts are frequently exchanged on the field.
That parents would specifically harass you in public for being a female playing on the field with males is a real throwback to the kind of racism I grew up with as a child and adolescent, when blacks were not allowed to do many of the things whites did or at least not together in the same places. I'm certainly sorry to hear that this kind of attitude is still around among some parents but your approach (show 'em and keep on lauging all the way to victory) is a very healthy one. I would hope that more reasonable parents would tell the intolerant cretins who yell sexist things at you that that kind of comment is out of line and to shut up. Best of luck this year in all that you do.
