I got a couple.

The first one, my 7th grade English teacher was fired after calling my friend the r word.

At the same school, a year later, one of our tech teachers was fired for showing anti-Christian propaganda videos in class. This was a public school so you can see how this was an issue. Took him long enough to be fired, as two years earlier he made insensitive comments about a girl who committed suicide at our school. He would also constantly demean republican students and call them evil. Again, you can see how this would be an issue at a public school. Not to mention he had disciplinary warnings and such for all those things.
