I have seen this my entire life on a small scale. Even since fucking school.
Action against you is justified, because teacher doesn't find it "actionable". But you will have to suffer it for next 10 years of your life. 10 years of suffering is HELL. It cannot continue like this, but noone cares. Unless you escalate.
But self defence is ALWAYS considered unjustified escalation. Why did you attack, he was only bullying you...
It's laughable.
