So one teacher accidentally outed himself because a kid was able to record him. How many others are out there, spreading this kind of attitude, that we never hear about?
That crap's been going on for a while. Even in 6th or 8th grade (1950s) I remember a teacher telling our young malleable minds that nobody needed to make more than $X* a year.
That stuck with me until college, where I finally started to actually think about it.
I suspect you'll hear more stuff like this after the woke people are awakened and start pushing back on the BS.
