Many of the circumstances being called out as concerning in recent weeks map well to historical examples—the framing of the argument alone doesn’t inherently invalidate it when we have good examples of comparable events (e.g. purge and installation of unqualified loyalists) precipitating critical, difficult to recover from outcomes (democratic backsliding) in other societies. When the stakes are so high, vigilance is rational.

Well, if you wait until that threshold is crossed, it's already too late!
