The exact same thing can be said for liberal communities. It becomes a hivemind where dissenting opinions are not allowed.
Take the Hunter Biden laptop story for instance. So many websites and communities outright banned it from being discussed or posted because they didn’t like the optics of it. Facebook banned it, the top subs on reddit banned it.
Only very recently has CNN decided to treat it as news, after lying about it constantly on air for months saying it was fake. That’s censorship of information. The left regularly spread misinformation like “the laptop story is a Russian hoax”.
