There are none so blind as those who refuse to see.

Her medals, fame and fortune won — presumably fairly — Simone Biles now has an international forum to advocate for unfair play, aka cheating.

Biles last week publicly trash-tweeted unabashed fair-play advocate Riley Gaines for her front-and-center activism to rid girls and women’s sports of former males increasingly competing as women in winning formerly level-fielded competitions.

Gaines — having finished second in the 2022 NCAA women’s swimming championships to Penn’s Lia Thomas, a 6-foot-1 trans who also swam on Penn’s men’s team — blew her whistle on behalf of other talented, trained and fully committed female athletes who have and continue to suffer a similar fate.
