An intersectionality cat-fight has erupted between world-famous drag queen RuPaul and transgender activists over his VH1 show "RuPaul's Drag Race" not allowing transgender contestants to compete.

Speaking with The Guardian, RuPaul said trans women should not compete on his show if they have begun transitioning.

"You can identify as a woman and say you’re transitioning, but it changes once you start changing your body," he said. "It takes on a different thing; it changes the whole concept of what we’re doing. We’ve had some girls who’ve had some injections in the face and maybe a little bit in the butt here and there, but they haven’t transitioned.”

After getting blasted by the Left, RuPaul apologized Monday on his Twitter account, calling transgenders "heroes" of the LGBTQ community.

“Each morning I pray to set aside everything I THINK I know, so I may have an open mind and a new experience,” he wrote. “I understand and regret the hurt I have caused. The trans community are heroes of our shared LGBTQ movement. You are my teachers.”

He added in a second tweet: “In the 10 years we’ve been casting Drag Race, the only thing we’ve ever screened for is charisma uniqueness nerve and talent. And that will never change.”

Despite the apology, RuPaul seemed to reinforce his position when he tweeted, “You can take performance enhancing drugs and still be an athlete, just not in the Olympics.”

In his interview with The Guardian, RuPaul also said that drag queens do more than just wear women's clothes, but rather as an act of protest against masculinity.

“Women don’t really dress like [drag queens]. We are wearing clothes that are hyperfeminine, that represent our culture’s synthetic idea of femininity,” he said. “Drag loses its sense of danger and its sense of irony once it’s not men doing it, because at its core it’s a social statement and a big f-you to male-dominated culture. So for men to do it, it’s really punk rock, because it’s a real rejection of masculinity.”
