While I would say that graph is more correct than the two-dimensional ones, many of us are fed in the west. (As a social libertarian/anarcho communist) I make the point that I don’t believe authoritarians actually qualify significantly for any form of left or right. They are all about their authority primarily and doing what they wish to do. They will resort to any rhetoric or means to achieve their goals they think will serve them. Whether it is left or right.
Case in point Hitler, who is closely associated with fascism which is considered nominally right-wing. Absolutely aped the terminology and rhetoric of early 20th century socialism. Till it didn’t serve him anymore. China who is more or less The Golden child of ml activists is more state capitalist than they are State communist. Because it suits those in power.
The graph more accurately might look like a deformed Dorito. Authoritarians being fluid and centrist. Not committed to being left or right. On the right side gradually sloping down through libertarians into capitalists/liberals on the far right. Somewhere neutral between authoritarian and actual libertarian. But the more true libertarian you trend the more left you absolutely trend. That’s for sure.
