The red cape

The real target of gender criticals are those who dare to usurp womanhood. They don't care as much about gender variant people who express themselves as they choose in public but once you talk about women's spaces and sports you have put the red cape before the bull. 

Decades ago transsexuals transitioned and disappeared into society and hence womanhood was necessary if you knew what was good for you. If you wanted to lead as close to a normal existence as possible, you didn't ever talk about your origins. People like Terri Noel (who began in female impersonation) married men post-transition who never knew their past. 

That young transgender woman whose video I featured recently is 9 years into transition and is not yet 30 and in this era the concept of stealth is almost impossible. She adopts the composite term describing her identity to make the distinction that her biology is different. But then biology doesn't determine how she feels (at least not her genitals) and she doesn't get hung up if people use biological arguments on her. They simply bounce off as irrelevant because she doesn't deny them.

What is particularly galling is that the percentage of people who fully medically transition are a small percentage of the people who express gender variance overall (which is already relatively small) making the moral panic around it very much about the idiocy of some humans who apparently have nothing better to target or worry about.
