>Most of the actual work to stop males from competing in women's sports, Males who transition to female are not males. They are female/women. It is already not permissible for men to compete in women-only sports. This became a national issue when many politicians and pundits saw a new vector to attack the trans community. We have heard it on campaign trails constantly for years now as if it’s some existential threat…
This is precisely the point of contention. The people who want women's sports leagues to be able to legally or socially-acceptably bar transwomen want this precisely because they do not consider trans women to have the meaningful female characteristics that justify having a female-specific sports league to begin with.
I'm personally ambivalent on this point, and it's because I don't actually care about women's sports one way or the other (I barely care about men's sports). But if you do care about women's sports, it doesn't seem unreasonable to me that you might have good reasons to want to restrict trans women from participating for the same reasons you want to restrict cis men from participating.
