This one is less ambiguous.
The accusation of “trolling” pisses me off. “Trolling” implies he doesn’t really mean it. It’s just fucking racist hate speech. “Libtards won’t admit the obvious, black kids are just inherently violent and stupid, and schools need to use harsher restraints on them to keep the school safe for the good type of children”. It’s a fig-leaf to blame “culture”.
That whole thread pissed me off so bad. This is literally a racist’s favorite story. Angelic WASP teachers, tied to a rock and sacrificed to tribal Africans. The recreational outrage is overwhelming.
