No.
Schools have MORE than enough money, they're just run by morons that don't spend it wisely and instead bolster admin pay and waste it on stupid seminars by grifters like Ibram Kendi.

Just because a social media account posted what they were doing and people got justifiably angry about it doesn't mean it's "right wing extremism".
You seem to be having a bit of cognitive dissonance going on. You're pointing out that public schools are a failure while simultaneously saying anyone questioning how they're run is obviously a "right wing extremist". How about placing the blame on the actual people running the schools instead of the people who are telling you why they suck.
