Olympic gold medalist Simone Biles got into it online with OutKick host Riley Gaines on Friday, and Gaines didn’t hold back in her response.

The exchange started after Gaines criticized a Minnesota high school softball team that won a state championship with a transgender pitcher on the mound.

Marissa Rothenberger, a biological male identifying as female, threw a shutout to help Champlin Park High School take the title.

Gaines, host of the “Gaines for Girls” podcast, pointed out that the Minnesota State High School League had turned off comments on their social media post featuring the team’s championship photo.

“To be expected when your star player is a boy,” Gaines wrote.

That’s when Simone Biles jumped in, attacking Gaines directly.

Biles called her “truly sick” for the post and claimed Gaines should be “uplifting” transgender athletes.

Gaines responded with a video message, and she didn’t pull any punches.

“Yesterday, Simone Biles — the Olympic gymnast, the best of the best, bar none; there is no one even remotely in her league — I guess, in an attempt to be inclusive and virtuous, decided to sell out all girls who have dreams to achieve and to succeed, and to specifically personally attack and body shame me,” Gaines said.

“Let’s get this straight. It’s my job. It’s the women’s job. This is what Simone Biles is saying: It’s the women’s job to find a way for the men’s feelings to be validated, for their identity to be affirmed. That’s not my job, actually, at all. So, to say I should be doing this is insane.

“If she wants to use her platform to uplift men and women’s sports, then, by all means. But it’s certainly not my job. And I don’t believe it’s the job of any woman to do this.”

Biles then doubled down, throwing a jab at Gaines over her well-known race against Lia Thomas, the transgender swimmer Gaines once competed against in 2022.

“All of this campaigning because you lost a race. Straight up sore loser,” Biles wrote.

“You should be uplifting the trans community and perhaps finding a way to make sports inclusive OR creating a new avenue where trans feel safe in sports. Maybe a transgender category IN ALL sports!! But instead… You bully them… One thing’s for sure is no one in sports is safe with you around!!!!!”

Biles also told Gaines to “bully someone your own size, which would ironically be a male.”

Gaines fired back again.

“Number one, she’s acknowledging there are differences, like physiological, biological differences, between men and women in saying this,” Gaines responded. “Secondly, I’m 5-foot-5, which might seem like a giant to someone who’s like, 4-foot-7, 4-foot-8, but I’m pretty standard size for a woman, just, like, relatively muscular, right? Being an athlete, I would imagine Simone would understand that.

“But I weigh like 135 pounds, 5-foot-5 of pretty much pure muscle. Again, if anyone would understand that, you would think it’s Simone Biles, a woman who has historically been scrutinized for having a very muscular, masculine-looking body.”

Despite the clash, Gaines credited Biles for her bravery in speaking out about the abuse she and others suffered at the hands of Team USA gymnastics doctor Larry Nassar, but said Biles’ current stance doesn’t add up.

“This is a woman who has been incredibly brave in calling out and witnessing the horrific sexual abuse that she and hundreds of other female gymnasts faced at the hands of one sexual predator — that predator being Larry Nassar — in the same breath, believing that vulnerable women should be forced to strip down naked in front of men and locker rooms, so long as it makes the man feel happy,” Gaines said.

“If Larry Nassar came out as trans, I don’t think it’s responsible or safe for him to be housed in a women’s prison.”
