Donald Trump Jr.’s new book that was released for sale on Amazon.com on Tuesday, Nov. 5. is called “Triggered: How the Left Thrives on Hate and Wants to Silence Us”

In it, Trump Jr. includes a cautionary warning about transgender athletes participating in women’s sports

“When we allow mediocre men to compete in women’s sports, we do a disservice to all the hardworking young women who have fought to get to where they are,” said Trump Jr.

Biologically male athletes identified as transgender are racking up accomplishments in girls and women’s sports.

In Connecticut two high school juniors, Terry Miller and Andraya Yearwood, who are biologically male, identified as transgender girls, took first and second place in the state open indoor track championships on Feb. 16 this year.

One of the female participants, high school junior Selina Soule said it was unfair to make female athletes compete against biologically male runners.

“We all know the outcome of the race before it even starts; it’s demoralizing,” said Soule, adding, “Athletics have always had extra rules to keep the competition fair.”

The fact is congressional Democrats have repeatedly downplayed transgender athletes’ biological advantages in female sports, declaring that transgendered females do not have any natural advantage over their female competitors.

In May, the Democrats’ Equality Act made “gender identity” a protected category under federal anti-discrimination laws, ignoring concerns about the impact of the bill on female athletes. The act would force public schools to include biological males who identify as transgender girls in women’s sports.

New Zealand researchers at the Department of Physiology, University of Otago demonstrated that high testosterone and other male physiology provided a performance advantage in sport, indicating that biological males or transgender women retain  that advantage. Their research paper was published in the Journal of Medical Ethics and also on the British Medical Journal (BMJ) website.
