Mary Gregory was born male, but now identifies as female. Now that Gregory has broken world records in women’s weightlifting, some people have pointed out the fact that biology provides an unfair advantage.

Transgender weightlifter smashes women’s world records, sparking backlash from Olympians

A transgender weightlifter is receiving backlash after racking up multiple wins during the 100% Raw Weightlifting Federation competition in Virginia over the weekend.

Mary Gregory, an American powerlifter and strength coach, took to Instagram on Sunday to announce she had gone “9 for 9” at the competition and broken four women’s world records: Masters world squat record, open world bench record, Masters world deadlift record and Masters world total record.

“Still processing, full meet recap to come a bit later,” she wrote, before thanking those who made her feat possible, including the competition’s organizers.

“A huge thank you to @raw_powerlifting_federation_ , from the bottom of my heart!” Gregory said. “As a transgender lifter I was unsure what to expect going into this meet and everyone- all the spotters, loaders, referees, staff, meet director, all made me welcome and treated me as just another female lifter- thank you!”

However, despite her own enthusiasm, Gregory’s win seems to have angered a few other athletes, including former British Olympic swimmer Sharron Davies and British track Olympian Kelly Holmes.

Here’s Gregory’s Instagram post:

It’s difficult to disagree with Ms. Davies on this. If people who were born male are allowed to compete in women’s sporting events, what is the point of women’s sporting events?
