I think some on the left act like cultists, but basically everyone on the right is in a full on cult and they either don't know it, or think it's a good thing.
I think the only ones on the left that truly fits that, are the tankies. And even then, can you truly call yourselves left if you're an authoritarian? See: Stethoscope theory
funny enough, I was only able to find references to this on lemmy. It seems the same as (or at least similar to) "horseshoe theory" from what I can tell.
Alternatively, someone who is posting unpopular shit gets downvoted of their own accord, and blames it on politics. Almost assuredly has shouted "leave politics out of blank" but then injects politics into everything.
they also usually get reported and then banned too from many subs, it is the reason why the filters are so frigging high its catching anyone even left and right, and innocent accs. and then it results in a site-wide ban they come crying on lemmy how they were banned because reddit is too woke? and another site about bane vasion(they call them being too woke), no its because of you and russian trolls is the reason reddits banning so many people.
