I'm actually glad to see the conclusion. Everybody wants to censor what they don't like. There are people who believe free speech is not the ultimate value, but rather to protect people from 'harm'. In this case 'harm' being ideas they don't agree with. The best stance is not to take a side, but to make sure both sides are civil in the expression of their beliefs.
Just because a belief is civilly expressed does not make it less harmful. For example: people casually believing that the Sandy Hook shooting was a conspiracy drummed up by the government is actively harmful to the families affected by that tragedy. What do you say to those people? How do you solve that problem? And how do you define 'civil'? Because different platforms have different ranges of civility as well.
Sticks and stones...
