As I said elsewhere, there’s an obvious reason for it:
It’s probably also relevant that this is how many conservatives operate - the new partisan narratives get parroted on relevant right-wing media and social media sites, and suddenly they’re all repeating the same lines virtually verbatim. Left-wingers don’t really operate like this (for better or worse); the “herding cats” analogy tends to apply (as well as the “circular firing squad” one).
