Do not be too quick to poo poo leftist professors. It takes a rare level of genius to make caca come out of that end. I would imagine their students have to bring some pretty big shovels to class. Think of all the genius that must pile up, pinched off by lips that should never be kissing their mothers (or spouses or anyone else). Those covid desk-shields must certainly come in handy when the professor gets going and the caca really starts to fly. The poor students in auditorium classes only get face masks, but at least that keeps the genius from getting in their mouths.
