this is a good video that is in depth on the topic, but the main points are: 1. this is the new issue that antitrans activists have moved on to now that the "bathroom panic" has become politically less viable - concerns about trans athletes are primarily external to the sports world and happening in america and the UK 2. ensuring fairness in sports is much more complicated than separating people "born male" and "born women" for a litany of reasons, and any good solution to the problem will need to be more complicated than either excluding trans people or allowing everybody to join anything they want (for example, establishing different groups based on physical differences that actually affect the sport in question akin to height/weight classes) the current culture war debate is deliberately framed in a way to make the issue seem like PC run amok loony left, yadda yadda, just like the bathroom panic was ("grown men pissing next to my little girl? how could this be!")
