Are you asking for proof that a speaker has a right to force other people to listen to their argument?

I read it as requesting exactly the opposite.

[pottersbasilisk]

any legal precedent one way or another. Ive heard of free speech but nothing either way about a right to be heard.

[delinka]

That's because there's no "right to be heard." Just because we have a right to speak freely doesn't mean we have a right to be listened to. You might be free to say whatever you like, but everyone else is free to ignore you; owners of publishing platforms are free to not publish your recorded words.

As I said, freedom of speech does not automatically transfer into a right to be heard.
