The only "side" interested in actual free speech currently is the "far right", unlike left leaning forums and media outlets which explicitly censor one particular point of view, regardless of whether it is backed by legitimate science which should be open to discussion.
Censorship has undeniably become a leftist problem, if you insist on reducing the high dimensional space of political leanings to a single myopic dimension. Unbelievable that in 2020 people are shamed for going to the last places on the internet where discourse is unrestricted.
