Rachel McKinnon, a biological male who identifies as a transgender woman (pictured above left) won a women’s world championship cycling event on Sunday, as The Daily Caller reported.

After winning the 2018 UCI Masters Track Cycling World Championships, held in Los Angeles, the cyclist tweeted, “First transgender woman world champion … ever.”

Rachel McKinnon, a professor at the College of Charleston in Charleston, South Carolina, where she studies “the norms of assertion” and feminism and feminist philosophy, won the women’s sprint in the age 35-39 age bracket, beating Caroline Van Heerikhuizen of the Netherlands and American cyclist Jennifer Wagner to take home the gold.

McKinnon told USA Today back in January that biological males should not have to suppress testosterone as a requirement for competing against women, as The Daily Caller noted.

“We cannot have a woman legally recognized as a trans woman in society, and not be recognized that way in sports,” McKinnon said.

“Focusing on performance advantage is largely irrelevant because this is a rights issue. We shouldn’t be worried about trans people taking over the Olympics. We should be worried about their fairness and human rights instead,” McKinnon noted.

It can be seen in McKinnon’s tweet that she is larger in frame and almost a head taller than the other two athletes who joined her on the podium.

McKinnon also compared restrictions on biological males competing in women’s events to racial segregation in the past.

“This is bigger than sports, and it’s about human rights,” McKinnon told USA Today.

“By catering to cisgender people’s views, that furthers transgender people’s oppression. When it comes to extending rights to a minority population, why would we ask the majority? I bet a lot of white people were pissed off when we desegregated sports racially and allowed black people. But they had to deal with it.”

One person on Twitter said, “Dear Dr. @rachelvmckinnon: I appreciate your desire to fight for fairness when it comes to transgender rights. Do you think though that the biological women who lost against you have a right to feel aggrieved when a biological male beats them in a women’s competition?”

The Journal of Applied Physiology indicates that men are, on average, larger and stronger than women and produce more testosterone. The average man’s testosterone level is about 10 times that of a woman.

The average man also has 26.4 more pounds of muscle than the average woman (72.6 vs. 46.2), 40 percent more muscle in the upper body, and 33 percent more in the lower body.

At this year’s Boston Marathon, held in April, trans athletes were able to compete in whatever gender they chose — instead of their biological sex. This year’s event featured at least five openly transgender women, according to the Boston Herald.

“We take people at their word. We register people as they specify themselves to be,” Tom Grilk, chief of the Boston Athletic Association, told the Associated Press at the time.

“Members of the LGBT community have had a lot to deal with over the years, and we’d rather not add to that burden.”
