I think these characteristics apply very well to broad swaths of humanity. They’re not limited to authoritarians.
I could make an argument that these characteristics apply to feminist support for Clinton. Clinton supporters and feminists would likely disagree, but my argument would resonate with others, just like these characteristics resonate with us when applied to Trump supporters.
My point is not that it’s incorrect to describe Trump supporters as authoritarians and utter fucking idiots and the greatest threat to Western Civilization since high fructose corn syrup. They obviously are. My point is that our worldview may be rooted in the same set of characteristics.
