Which is an non-issue.
But I can see how this is their interpretation of "trans".
All they have to do is to clarify that only "biological females" are allowed to play in the WNBA even if they identify as "men".
But of course they're not doing that.
I think the issue is this, the WNBA already has people who were born men playing in the league and if challenged in court would have a difficult time defending keeping Enes Kantor and Royce White out of the league.
Social media speculation is that Britney Griner is really a biological male, this is the person who was caught with drugs in Russia and sent to prison, later Biden swapped Victor Bout an arms dealer for Griner in order to get her released.
