Banning trans women from competing in sports it telling them they aren't "real" women. The societal repercussions of that are much larger than the outcome of high school athletics (and this issue is almost always about high school athletics and below). I fundamentally don't understand arguments to the contrary.

For the record, I care deeply about sports. I think it is fundamental part of both our culture at large and the education of a lot of people. You can dig deep into my comment history on HN and see I regularly defend the importance of sports to the usually derogatory "sportsball" comments that are common in intellectual and technological communities like HN. I just don't think the outcome of specific games is important enough to justify further ostracizing a group of people who are already incredibly marginalized.
