Sports leagues will continue to ignore a fan - a hardcore fan, no less, as his username indicates - as completely unimportant to the sport? Really? Who are you to say that, and for what reason?
And another thing the sports leagues will not continue to ignore as completely unimportant to the sport as the Women's Lib Movement (look that archaic social movement up for funziez) can attest are protests, boycotts, and even more, lawsuits. An unfair sexist situation lawsuit here, a severe injury suit there, and THE reason for F/M segregated sports in the first place will become become readily apparent for all in attendance including those short of a refresher course,,,
Some people may pretend they've forgotten the reason why there are sports teams separated along biological gender lines to begin with, but most haven't. Adopting an overly confrontational attitude will do nothing but push the reaction against it even harder.
