For instance, there was a video about a girl punching another racist girl. People were saying the racist Karen got what she deserved.
Or people getting into fights because ''he talked about my mother'' thing.
That contradicts the very concept that assaulting others not in self-defense is wrong. Someone talking bad about your mother, calling you stupid or telling you racist remarks isn't self-defense. You still did your part in turning an verbal situation into a physical altercation. It's still wrong to hit others for being antagonistic jerks. Yes they said mean stuff but you started hitting.
