I am more than confident that Flynn knows what he is doing. I think if anons stopped thinking of themselves as inconsequential players and Flynn as some sort of "influencer", and began to think of anons has having a critical mission and Flynn as an actual general speaking to us, they might begin to appreciate his tone.

Think drill sergeant.

We can be sure that Flynn is as tough as grits, and if he's rough and tough with anons, saying harsh things and even things that go against our grain, its because its necessary. Do you think that the drill sergeant who tells his platoon that they are crap, they are shit, they are useless scum - that he really believes it? No.

He is a very tough general (one of the toughest) talking to his troops, and frankly, this is war.
