The thumbnail is using the political compass as a way to assign well known personalities to political ideology. Lenin for authoritarian left, Trump for autoritarian right, Elmo for liberarian right and ?/nobody for libertarian left. We could discuss these placements, but the main point is that for libertarian left aka anarchism there is no leader assigned
Also thumbnails might be different for different users because of A/B testing from YouTubers or just normal updates/changes to the video by the creator
I agree, but Andrew makes a very careful distinction between leaders (in the sense discussed in the video) and bosses, and correctly identifies that there are still risks of hierarchies developing out of anarchistic leaders. One of the YouTube comments makes a point that a better word for Andrew's concept of "leader" in his video would be "guide". For talking about this concept in English, I agree with that commenter, but otherwise I also agree with Andrew's take.
Oh yes, we watched it and we agree. We have to be very careful otherwise heirarchies can easily form if we aren't fully commited to making sure they don't.
We were part of an 'anarchist' group once but we left because two people became the defacto 'leaders' and kept telling us that we couldn't do things without ever explaining what they meant beyond just saying that we couldn't (in a more specific way but we don't want to let on should they ever find this).
Between that and the red tape we don't really trust most 'anarchist' 'organisations' and prefer to just get things done ourselves.
