WATCH: Mother and daughter athletes speak out against the inclusion of biological males in women’s sports on Tucker Carlson

Hubbard is a biological male who at 43 will also be one of the oldest Olympians competing. Hubbard will compete against young women in their 20s. Hubbard will the first transgender athlete to compete in the Olympic Games.

Cynthia Monteleone described her experience representing the US at an international track and field competition in Spain. Her daughter had the same experience, but in high school. A 10th grade track athlete, Reese Monteleone lost out to a biological male competing in women's sports. They spoke out in an attempt to save women's sports.

In response to why she has chosen to speak up, Cynthia said that most mainstream outlets are not allowing women who take issue with biological male competing in women's sports to speak out. The idea is that it is more compassionate to allow biological males access to both the podium and the microphone and to silence women than it is to let women compete on a fair playing field.

"We're here to speak up and to say it happening, it happened to me to me and it's happening to my daughter," Cynthia said. "And this is a very dangerous issue. Not only can it be physically dangerous for girls in some sports, but it's dangerous to the whole concept of women's sports. Basically, this means the end of women's sports if this keeps happening."

"If not the end of women," Carlson said, making a point that gender critical feminists and conservative women have been making for more than a decade. "I think we're challenging the category itself. What is a woman? Well, it's whatever you say it is, I guess."

This has been an issue across culture, as not only sports, but legislation, has come down hard against the idea that there's any such thing as a woman at all. In Canada, the government refuses to define the term at all.

The US House of Representatives has substituted the term "birthing person" for mother, as has the Biden administration. The feeling from women's groups, politicians, libraries, and even corporations, is that women are a negligible entity compared to those biological men who identify as transgender and present themselves as women.

"We know from science," Cynthia said, "that even after—let me be clear—even after hormone treatments and gender reassignment surgery, male-bodied athletes still have an advantage over female athletes. Frankly, we don't need science to tell us that, it's common sense, and instinct."

"I feel badly for the girls I coach," she said, "when they're psychologically distraught having to line up against a biological male in their race. I have compassion for all athletes, including these females who are being displaced."

Carlson asked for an explanation of the advantage biological males have over girls. Cynthia detailed the changes, that start when a child is in utero. Males have a smaller hip structure, greater bone density and muscle mass. Males are not assigned male once they are born, instead, they are male before they even leave their mothers' bodies. Puberty is not the only factor in males' superior strength.

"No magic wand can erase these things," Cynthia said. "We are really grateful to the IWF [Independent Women's Forum] for telling our story, and for you for sharing our story."

Cynthia said that "we need fairness in women's sports, we need equal opportunity in women's sports, and these advantages are erasing those opportunities."

"You don't get fairness, you don't get equal opportunity, without courage, you don't get anything without courage," Carlson said. "You get controlled, and bossed around."

He asked Reese what kind of reaction she's received, being a young women who is speaking out against the inclusion of biological males in women's sports.

"I've received mostly support from my fellow athletes and teammates, especially on my track team," she said. "Because girls like me have had to race against these athletes. Other mainstream media might try to shut us up or tell us to not share our message, but I believe that I'm standing up for what I believe in and I'm fighting for a fair playing field in women's sports."

"You'd think you'd be a hero, the 10th grader telling the truth," Carlson said.

Reese said that her teachers were on board as well, because she may not be able to earn scholarships and opportunities due to losing out to biological males in women's competitions.

"We tell girls you have a voice you should use it, even if NBC doesn't like it," Carlson said, noting that he was glad to hear that Reese hadn't been subjected to intimidation, but had been supported.

Those who don't want to see the end of women's sports or of the ability for women to compete on an even playing field have taken issue with Hubbard's inclusion on the the team, which is comprised of Kanah Andrews-Nahu in the women's under 87kg division, Laurel Hubbard competing in the women's above 87kg division, Megan Signal for women's under 76kg, David Liti competing in the men's over 109kg division, and and Cameron McTaggart for the men's under 81kg.

Hubbard competed in men's weightlifting prior to transitioning at the age of 35. Hubbard did not make the Olympic team as a man. Hubbard was one of five athletes named to New Zealand's Olympic weight lifting team.
