Came here to make a similar point. Both political sides in the US can point to the observations in the excerpt as chilling historical illustrations of current and potential near-term events. That illustrates in my mind what is so terrifying right now. That there is something bigger going on than political ideology and I don't think anyone can stop it. In fact I would posit that thinking so makes it all the less likely to be stopped. This is because either side will identify a different source of the problem and both will be wrong.
