Can a public school teacher call his/her students any name they wish? (actual court case)

Just because I was curious, a little googling suggested numbers in the area of .6% of US adults identifying as transgender.

Here’s one source that estimates .73% of kids 13-17.

No, I don’t want any kid to be unnecessarily harmed, threatened, or ostracized. But it seems we are placing evermore tasks on our educators these days. When populations get well under 1%, it doesn’t break my heart to suggest that public schools need to little or nothing to afford special treatment to those kids.
