It seems to me that this man changed his legal sex deliberately, as a get out clause, for when people catch him perving on women and girls in single sex spaces.
The rest of the time, he's just Joe Bloggs, normal chap, with male pronouns, and a regular heterosexual sex life. And a penchant for sex offending, of course.
A few years ago, I asked one of the wishy-washy politicians on a web chat here, what would happen if a man, in a female changing room, complete with penis, moisturises his legs after a swim, as women often do, and starts to make eye contact with all the women as he rubs his thighs or his towel falls off, as it might do with a woman, but he's got an erection?
There are absolutely no laws against women moisturising their legs, or being naked in a communal changing room, or looking at people.
But women do not constitute the predator class.
Transactivism has done such a number on people, convincing them that men and women pose the same threat.
