you also didn't answer the first part of that - which dystopian governmental overreach you're advocating for that would solve that particular problem?

if a teacher is doing it in public then remove the teacher? if it happens in private you can't do anything about it anyway so your problem is just a mental masturbation to create public outrage because of course every measure taken is there to protect the poor kid. Even tho the kid will still get fucked, equally it not more. Except that his cousin will also end up in jail because he tweeted about something you dont like.

all your arguments are based on the fact that human beings are the only animal in the world who cannot establish order without outside structure of the government which should be responsible for everything

no amount of random examples that cannot be solved for you give will make your authoritarian justifications any less horrible.
