This what they want ^^^ ???
Somethings cannot be put into a specific "bucket" so this would simply go into the catch all bucket labeled "hostile act".
The parents should ask for their school taxes back and file a civil suit to re-collect these taxes that they basically are now stealing from them. When denied a refund...go to court and ask for a jury trial and also seek damages.
I'd give them zillions as a jurist.
