One thing that is often lost with the free speech argument is amplification. For example, no one is stopping most people from going and yelling on a street corner. But that doesn't mean that you need to be allowed to speak in a particular venue or platform. Our society is currently not one in which there is a right to "equal volume" on speech, and I think that's a good thing.

The entire free speech movement was a response to government literally throwing people in jail for even talking about a given topic. It was never about allowing minority opinions to be as loud as majority opinions.
