>>> Do you have a source for these counter protests being organized and dictated by IRGC?

Basic logic and a pair of eyeballs.

They're about as brazen and blatant as these sorts of things get. No, I don't have recordings of the mullahs instructing IRGC what to do, but the pro regime protests are uniform and exactly what a mullah would want for pro regime propaganda, with none of the nuance or variability you'd expect with spontaneous, grassroots support.

As far as I know, there's no documentary proof, but the evidence implicit to the structure, timing, messaging, location, and demographics are more than sufficient to damn them as regime orchestrated agitprop as opposed to any genuine opposition to the anti-regime movement.
