The most decorated American Olympic gymnast in history, Simone Biles, may have bit off more than she could chew over the weekend when she hypocritically took aim at the woman touting the same kind of sex-specific protections that paved the way for her domination on the mat, beam, and vault.

The fallout started when Biles used her Friday night to snipe at prominent women’s sports defender Riley Gaines as a “bully.” Biles was upset that Gaines noticed the Minnesota State High School League turned off the comments on a post celebrating the victory of a softball team whose “star player is a boy.”

“[B]ully someone your own size, which would ironically be a male,” Biles wrote on X, tagging Gaines.
