if a racist said they didn’t want to play with black people
If the larger community proposed a restricted class for black people, we would still listen to black people about whether they thought it was a good idea, not the racists.
The previous commenters’ statement that we need to listen to the women in the women’s restricted participation class, with respect to rule changes for the women’s restricted class, is valid. I think you’ve jumped to a conclusion that women chess players would oppose including trans chess players, without a basis in fact. It’s not clear to me that proposed restrictions on trans participation are actually coming from women participants.
But if women players are concerned about the effect of including trans players (whatever effect that may be), clearly we should listen to them. The limited participation women’s class exists to serve the needs of the women in that class.
