> Huh? What "moral panics" proved what exactly wrong?

I think they are referring to moral panics around violent video games and the idea that shooting a player in a video game they teaches people to be violent in real life.

It seems like you are making an analogous argument, that being mean to Claude teaches people to be mean in real life.

In my opinion, being an asshole has a way of self-correcting. People will not want to hang out with you anymore if you suddenly browbeat them at a dinner party. So I am not that concerned about this.
