… But where is that women’s football league that excludes cis women while still calling itself “[just] women’s football”?

Whereas we already have many women’s leagues in sports that exclude trans women.

So if it’s actually happening, then sure I’ll agree to calling it “taking a title” and honestly be against it; imo it sets the fight for trans rights back if we use “woman” exclusively for trans women and cis women only ever get called “cis women”. But again, where is that happening? Who is calling for that?

I only ever see people claiming that cis women should have exclusive use of the word “women”, not the other way around. Which is just another way of arguing that trans women “aren’t really women”…

Trans women are women, and cis women are women. Simple. No one is “taking” someone else’s name.
