When people stop reacting to them.

I doubt being silence makes bullies shut up. Generally, they show up in favorable environments, where the voice of reason is absent, and no adult is caring about what's going on in the room. But being just silence? Just makes them worse.

I'm not talking about the people who you think are "adults" (I assume you mean people whose opinions mostly matches yours), I mean everyone. They wouldn't talk about this if nobody was listening.

And people wouldn't listen to them if they talked about things that are not problems.
