Out of those reasons teachers were fired, the only one I can really understand would be maybe the last 3 or so, especially calling a parents the "c" word. I think I recall a few of those being from private religious schools (at least the getting pregnant while being unwed).

It really is quite terrible that that's how teachers are viewed and that something like posing on a yacht in a swimsuit or posting a photo of them (assumingly over age) drinking wine on vacation would get them fired. That's just totally and completely wrong.
