I of course can't say anything about your case. I just know that from the other side, it's incredibly difficult to tell. We take it very seriously every time mobbing comes up. But I would say in 95% of the cases, we are honestly not sure who is really the victim. And even when we are sure, it's incredibly hard to stop it...

Apart from that, physical assault should always be stopped.

Not to mention the selection bias here. 

How many millions of kids go to school every day and leave without incident? 

How many tens of thousands of fights are stopped before they happen through tier one intervention, social emotional learning, and teacher action? 

How many of the fights that do happen have clear victims and assailants? 

This is the worst kind of echo chamber that magnifies a few bad (and likely one-sided) experiences and makes them out to be "universal" or "the norm".
