A male ex-soldier punched and choked a woman in the name of sport.

Alana McLaughlin, the second openly transgender woman to compete in MMA in the United States, won her debut on Friday night via submission at the Combate Global prelims.

The 38-year-old used a rear-naked choke against Celine Provost to end the match three minutes, 32 seconds into the second round.

After finding it near impossible to find a female opponent, McLaughlin agreed to fight Provost, who stepped up and stayed in the ring as long as she could.

McLaughlin began transitioning after he left the army in 2010. He says it was a fair fight because the board cleared him after ensuring lowered testosterone levels. His muscle mass and memory, heart and lung capacity, xy chromosomes, and other advantageous traits of being a biological male who has trained at elite levels was totally disregarded.

The biological male is determined that others join him in women’s sports.

“If we want to see more trans athletes, if we want to see more opportunities for trans kids, we’re going to have to work our way into those spaces and make it happen,” McLaughlin told Outsports.

“It’s time for trans folks to be in sports and be more normalised.”

Binary spokeswoman, Kirralie Smith, said his win was offensive and dangerous to women.

“Women’s sports must be kept for women,” she said.

“Female athletes need to stop participating against males who appropriate womanhood.

“It is unfair and unsafe and it will not stop until female athletes and their supporters draw a line in the sand.”
