It's the equivalence of accusing somebody of repeating ruling ideology talking points.
It's a decent rhetorical device, it would probably be better to make it a verb to denote that it's something that people did, rather than something they are.
The entire tactic of destroying leftist space with accusatory spirals, can be avoided if you focus on actions, you know say to people, you are doing something wrong, rather than saying you are a "wrong-person".
They aren't doing much beyond pushing the button that triggers the clerical instinct to excommunicate.
if you focus on actions this is bypassed.
