On the contrary. Women won’t boycott to stand up for themselves, so they’ve left it up to men like this guy to highlight the ridiculousness of the situation.
If he didn’t join the tournament, it would just be a matter of time before a real tranny did, but then there would only be praise for the tranny and no criticism allowed. A regular man joining at least allows the women to speak out against the situation without repercussions.
I suspect maybe they have no regard for the trans idiocy and seek to mock it at every opportunity. Taking something to its absurd limit often works.
