Because the post started off inflammatory and stupid. Schools barely mention trans people, but if they did it would take one lesson. And if half a percent or one percent of people are trans that seems like it's worth the time. Also not being distracted by dysphoria should help with learning effectively.

There's a lot of talking points that don't come at the expense of real education at all. If you want to discuss real problems let's look at school district funding and curriculums that are overly focused on standardized test results. You don't need to make fun of non-binary people as if that's some kind of wasteful hobby rather than just an attribute.

With all due respect, altho it may seem that it was to you, I do not thing it was very relevant.
