The only people exhibiting any kind of shock over this are literally only leftists. No Republican here is showing any kind of shock or (?) disappointment.
Then I will be the first to do so. This was a bad joke and not funny. It has a large downside for teachers to be offended. I know my Mom would be offended if she heard this. And there is really no upside here. It wasn't some fatal disaster, but it was an unforced error.
Wouldn't anyone in education have stories about nasty stuff said in teachers lounges?
