Can you support the assertion that it is mob dynamics and not just aggregation of a bunch of individual decisions.
This is a fantastic question, and I’m not sure I have a rigorous, testable, objective answer.
From my perspective, it looks, feels, sounds, and smells like mob dynamics. A recent Quillette piece lays out some specifics about how and why the SJW element acts as a mob:

..which is not to say that the SJW echo chamber is the only echo chamber acting mobish. I think they all are.
As to how to objectively measure that, I don’t really know. I’m not sure how one would go about it. How do you quantify mob behavior in a measurable way? It would be a fascinating question for a social scientist to try and answer, although he’d have to worry about retribution from the mob for simply asking the question, and the social sciences are definitely trending more towards mobish behavior within the last five years, so that in itself is a barrier to answering the question rationally.
