second - fishin', "boys teams" and "girls teams" are there because sport is not politics, economy or any other area where female should and must have equal chances and opportunities.
if you are planning to make unisex sports teams then you will have one female athlete for 1,000 male athletes.
Marion Jones is top class athlete and she deserves all atention she gets, but if it would be society without "boys teams", and therefore "boys competitions", Marion Jones would not be in Top 1000 runners. This is NOT my or anyone opinion, this is pure statistical fact - she rans 10,8 at best on 100 meters - male records in probably every country in the world are better and in USA alone are probably hundreds of males faster then her.
So several billion females from around the world should be denied the opportunitty to participate simply because of their gender and the fact that there are men who will beat them 99 times out of 100 should they reach the utmost levels in their chosen sport??
Maybe Marion Jones wouldn't be at the top of the pile. So what? (And when did Marion Jones become a "team"?) Should every 5 year old female be denied the opportunity to play soccer, basketball, baseball, bowling, volleyball, etc.. against males that are just as lousy at it as they are?
So, what do you think would unisex sport bring for females?
Maybe the opportunity for millions of kids to play together, have fun and figure out that they aren't all that different. And that works for males just as well as it does for females. But I guess the idea of particpating in sports for the purpose of having fun never crossed your mind. It seems you only focus on sports when there is money involved. Not everything in life has to be related to making a buck.
By the way, Marion Jones' personal best at the 100m is 10.65. That would put her at #17 of all time in the Olympic record book when merged with the men's list. Flo Joyner's Olympic time would put her at #15 slot on that list. I doubt there are 1000 men in the world right now that could make the same claim.
