I have always told my kids they do *not* start fights but they sure as fuck finish them. Someone hits you you make you sure they can’t hit you again. 

We’ve had some bullying problems. One of my kids is the type to bottle it up and ignore it until they snap. I talked to the school about the billy multiple times. Eventually I told them “my kid is going to snap one day and turn around and punch her in the face and I’m not going to say they were wrong. And my child will not be getting in trouble for it either”. Sometimes going full Karen is warranted.

Not to sound like a nerd, but I appreciate the Ender Wiggin approach to bullies. Be pragmatic and hurt them way more than they intend to hurt you. Don't throw a punch. Instead, grasp their arm and break it. Not only will it end the fight quickly, but they won't mess with you again afterwards.

Note: I've never actually done this lol
