What I wanted to focus on is that it is not true that free speech is the solution to all democratic problems, it's not an absolute good. We limit speech already, you can't advocate for the killing of other people, races, etc...
Also, about free speech, if you can say what you want but there are very large entities controlling who gets to hear what you say, then in a way censorship might be already happening. In this case non-arousing messages are being suppressed because they don't make money, so we all feel like everybody is either pro-this or against-this, and they're all really mad and or dangerous.
This is not an easy problem to solve.
