I saw some "liberal" nonsense spouted by a few teachers when I was in school, though nothing as insane as what's being pushed today. It didn't take very well, since we were children of the WWII generation and in most cases our parent's down-to-earth realism rubbed off on us.
When I read about what's going on in some schools these days, I find myself thinking it's time to bring out the tar and feathers again . . .
