Why do they go to a reference of birth gender, why not by chromosome?

Class for XX and class for XY. That’s it. Put it on bathroom doors.

Nobody wants to hear about what they think they are at this minute, just go by do you have a Y chromosome or not.

And it's still the wrong answer since FtM shouldn't be in the girls division either. Just have an open division Yes, at elite levels, an open division will look an awful lot like a men's division -- because gender dimorphism is a thing. That's God's doing, and government can't repeal the laws of nature. Let the girly girls division restrict eligibility and ban Y chromosomes, penises, and testosterone supplements.

Everybody has a right to play sports, even trannies. No one has a right to be a champion, so suck it up and join the co-ed rec league with everyone else who will never play on TV.

Since We're all the same now, just have sports open to everyone, no mens and women's. Nobody watches women's sports anyway. They can get back into the kitchen where they belong.

aka biological men cannot pretend to be women in women's sports. Women wouldn't want to compete with men, they'd never win and get pummeled in physical games.

So how does this differ from the she vetoed earlier in the year?

People are suing and changung their birth certificates

all any sane person would have to look at is the world records between the two genders, they are not the fucking same. its illegal to dose with testosterone but when your body makes it naturally thats fine

we should not class on gender. as they can fight that. use 'science'. muscle density, bone density, etc. cant fight that shit.

according to their birth gender

According to their sex, which can't change.
