Minnesota is the first; it surely won't be the last

A female fencer took a knee instead of competing against a biological male, leading USA Fencing to disqualify and expel her from the college tournament, despite her opponent having played on the men’s team last year before switching to women’s.

If We Can't Have Men in Women's Sports, Then We Will Have No Women's Sports at All...

The USA Fencing Minnesota division announced plans to only sanction mixed-gender events moving forward in response to new policies that prevent biologically male trans athletes from competing in women's competitions. 

USA Fencing changed its policies to ensure that only biological females are able to compete in the women's category last month after the entire U.S. Olympic and Paralympic Committee (USOPC) updated its athlete safety policy to suggest compliance with President Donald Trump's "Keeping Men Out of Women's Sports" executive order. 

David Strom:

As a practical matter, of course, the real victims of Minnesota Fencing's decision are women who should be allowed to compete with other women. But that is no barrier to making this change to their policy, because these women are "cisgender," and hence lower on the intersectional ladder than transgender "women." 

This is what they call "equity."
