I live in Richmond Virginia and I strongly oppose this petition.

As a full-time fitness professional, certified personal trainer and former collegiate athlete who has trained athletes of many genders--including trans athletes--I'm well-qualified to speak to the fact that trans women are women and deserve a place in women's sport.

Furthermore, the idea the biological sex is 1) strictly binary and 2) easily determined that this petition is based on in deeply flawed. Using a broad definition of intersex (including those individuals who have only a single X chromosome), approximately 1.7% of the population displays some degree of deviation from the general pattern of sexual dimorphism. And if we include things like PCOS, an endocrine disorder which according American College of Sports Medicine may lead to advantage in sports performance, we see more than 10% of the population of cis women affected.

Attempting to police the sex and gender of athletes will only lead to preventable harm, including harm towards cis women as well: we need only to look towards the harassment of Olympian Imane Khelif for evidence of that.
