It certainly describes certain groups' political behavior more than others. I think the "centrist lanyards" (or whatever we might call them) may even view endless reaction as a *positive* way to experience the world when it's rebranded as "pragmatism" or "realism".

Right but “realism” as a descriptor is less preferable due to being completely inaccurate

Ditto pragmatism. You want pragmatism? You’re looking for Lenin.
