Gender activists love using hyenas as examples to deconstruct the binary system of sex. But, like all their other examples, the hyena actually reinforces the biological definition of sex. Take a listen. Preview from my new audiobook releasing very soon!

Humans, like 95% of other animal species, are gonochoric. Our sex is fixed for life. Some species, such as the clownfish, can change sex, but humans did not evolve the genetic or developmental plasticity for this.

External genitalia is an accurate marker of sex in 99.99% of births. The sex of the remaining 0.01% can be determined through analysis of their genetics, gonad type, and internal genitalia. An example would be a baby presenting with ambiguous genitalia. In this example, further

Zohran Mamdani will likely win the mayoral NYC primary for the Democrat party. He plans to use $65M in taxpayer funds for cross-sex hormones and surgeries for minors while using the State to conduct investigations and hearings against hospitals who fail to do these procedures.
