This is what is so disingenuous about its "argument". (And the only reason Dion likes the word arguMENt is pretty clear, butt i digress...)
When any professional league was established, it was clear some people would not be able to compete. Many of those people happened to be women. So women came together (and excluded men), because they wanted a chance to play competitive sports. And they created lesser leagues ... this is why the women's soccer team argument is SO stupid. But now liberals and men are invading and taking over their leagues and it is inherently unfair. Could people under 5' start a hoops league? Yes they could (and it might be FAS, I might actually watch it). West Point used to have a "under 150" football IM league. Many schools have rugby "clubs" ... it is fair and they mostly establish the rules.
And it is terribly juvenile to argue otherwise.
