Why be denied because of whom we are? (Girl or Guy)

      From an early age we've been told "Oh no! boys have cooties. Don't touch" or most importantly "Girls have cooties! Run away!" We're all guilty to of said this at one point in time in life. Not to mention all girls have been told "You're a girl. You can't play with us" Well, why can't we?
      There is always somethings a girl can do that a guy can't. And, of course vise verse but, now one of the biggest sports that determine this set of mind is football. The good ole' American sport that has been played since only god knows when. Girls do and have played football from the little league but when it comes to junior high through college even pro. Girls are just meant to be a cheerleader or on the dance team and even in the crowd cheering our boys on. But, what about the guys that could be in the crowd or on the cheer squad cheering on their girl? Now, there are many guy cheerleaders, dancers and ballet performers. But, aren't those supposed to be girls and young woman doing this. Yet, we do not deny that they are forbid from doing these activities. I do agree. We have came a LONG ways from the1800's to 1930's where women had barely no rights at all. Hopefully, one day woman can play this game with pride one day. Just one more thing to add on to the list of things that we can do.
