Admittedly, I’m not thinking about just chess, but the overall argument of how to classify and allow trans folks to participate in competitive events. I don’t see a big difference between trans people in chess vs swimming or basketball.
Regardless of how you want to frame the discussion, it’s this argument they put forward to justify banning trans people. You seem to want to ignore it entirely. I really think that’s unwise, and I’m looking for some kind of potential solution to actually address it.
I think, overall, and regardless of how popular it is, this method of ignoring opposition arguments is very detrimental. 90% of the country’s land area has never seen a trans person in real life, so the arguments they read about are all they have.
