I don't get why it's so hard for some folks. You can identify however you want, but if you're sex is male and you have a wang and nuggets, then you don't try and run, jump and throw against girls. How selfish can someone be? It's boys bullying girls because they suddenly decide or think they are themselves a girl.
I realize some trans are serious, and that's fine for most things in life. But not competing against biological girls or dressing in their locker rooms.
If you do the hormone treatment thing, that I think there are considerations to be made and I'm not opposed to agreed-upon levels of testosterone, etc. that indicate transition to a female state. Those who do that ain't beating any championship-level girls anyway.
I mean one of these days a 4:15 miler or 10.70 100m runner or 6-7 high jumper or 56-foot shot putter is going to decide they're a girl and start smashing national records. We've had biological boys win state titles already, including one running 52+ for 400m. But wait until an even more talented boy gets in there who can take records out to places no girl could reach (but isn't good enough for a boys national title). Then I hope everyone finally comes to their senses.
Peace out, bros.
