The author cites being "born into a generation that was still processing the collective experience and traumas of fascism" (in Germany) as a foundational experience for understanding the need for something like sociocracy.

My mind went to a paper I read ages ago that described the origins of neoliberalism as an antidote to fascism (looking questionable now).

So my understanding of fascism is like a humanity-level collective vice we are prone to, and constantly need to be organizing against.
