As more mainstream libs are discovering Lemmy, we're seeing a pattern of complaints that opinions outside the ones they deem acceptable are allowed on the platform. We've even seen instances defederating because their userbase does not wish to be exposed to these views.
Interestingly, these are the same people who level censorship and control of free speech as their main critique of communists. What we're seeing is that these people absolutely don't care about free speech. They understand the necessity of censorship and actively advocate censoring opinions that they find dangerous. Yet, when societies based on values different from their own use these same tools they screech about authoritarianism.
Turns out it's not authoritarianism libs hate, but having their own views censored. What actually offends them about places like China is that it's their ideology that's being suppressed there.
That's a really important point actually. Having implicit power structures form without any formal method of recall is precisely what allows unjust hierarchies to come into being. When there are no explicit hierarchies then implicit ones necessarily arise because some individuals are more charismatic and extroverted than others, and people tend to rally around them.
