Counterpoint. Although there is a rational basis for objecting to "biological men" competing in "biological women's" sports, that is not why the trans issue is being pushed by certain political groups. The real reason is to demonize and dehumanize trans people and to deflect attention from the fact that trans people have a right to exist unmolested as a fundamental human right.
A sort of analog situation was some years ago when steroids seemed to permeate baseball, and doping cycling. No one made a partisan political issue out of that, it was largely left to MLB and the sports regulating bodies. Because that is not an inherently governmental issue. But it's not any "fun" to demonize cheating baseball players or cyclists as a group, and doesn't serve any political purpose.
As noted, the right has thoroughly adopted the politics of demonizing and dehumanizing minorities, because it works among a certain segment of the population.
When you have ostensible national leaders squawking incessantly about threats posed by "trannies," and others, it enables and emboldens the real pieces of shit, like this bunch, to do shit like this.
