>> How does even harmful speech (e.g. your examples) prevent your freedom of expression?

Fear, threat of property and physical harm.

So...eat the rich? Seize the means of production? ACAB? Things like that qualify?

That is not the same thing though is it. People today fear being socially ostracized or losing a career over crossing an undefined or subjective line.

Neither of these fears are the same as actually preventing someone from expressing their views.

When threats become actual violence there are already laws to address that. Trying to preemptively protect people from mean words invariably harms more people than it purports to protect.

>When threats become actual violence

Only physical violence or does psychological violence count too?

What about cyberbullying and mobbing?

Ever heard of bullying?

You don't need physical force for that.

Bullying is an additional level of action, right? If you're using a different verb it probably also means additional actions that aren't simply speech.

I dislike bad stuff too. Bullying is wrong and should be stopped. Hate speech is also wrong but I'll defend people's right to speak.

"Bullying" is actually a great example of something that once we decide the concept is bad, there is a rush from people to frame everything they don't like along those lines. I'd suggest that under the blanket and nebulous headline of "bullying" are actions that are already illegal like harassment and assault.
