Unfortunately, this topic is bound to come up over and over in any discussion of female sports, as transphobia is more common than it's ever been. Deleting those posts regularly is probably a good idea for a friendly forum like this, just to keep things civil and on-topic, but the fact of the matter is that politics is engraining itself into more and more aspects of everyday life.
Mods, do what you have to do, and your work is much appreciated, but—and I hate to say it—I guarantee this won't be the last time this thread ventures to controversial territory, at least until more firm anti-bigotry rules are created.
