And Twitter is not politically biased? At least we vote for government officials. None of us vote for the Twitter mods who censor mainstream political discourse.
I'm an anarchist and most other anarchist-leaning folks I know with Twitter accounts have been banned at one time or another. Turns out intentionally violating platform rules does that. :)
Tankies, though, I don't know whether they tend to get banned.
There are many people that believe Twitter is biased in favor of conservatives simply because it allows some conservatives to speak at all...
