I hope someone shows up in that thread and says, "I'm a 38 year old mother of three. All my life, I've been training to be the best I could be at track cycling. Then one day, this doughy, out of shape hulking male ogre showed up calling himself a woman, and for some reason I'll never understand, people were OK with letting him compete against women in my first competition. He showed up in Spandex with a visible gut, and his chin was like Jay Leno's or Bruce Campbell's. Anyway, after decades of training, I went out and thought, "Well this isn't fair at all, but I'll give it my best!"
I came in 4th. He took one of the spots on the podium instead of me. And then did it again. And again, and again... and then I just gave up. I haven't been on a bike since. He crushed my dreams, and when I raised the thought that just maybe this wasn't a fair situation, he called me a bigot! And then he found a bunch of other, equally male people who pretend to be women to gang up on me and send me death threats and rape threats for just saying what was true. Now I don't interact with anyone any more, and I wish I had never taken up cycling in the first place."
