Man, if you've followed Iran, you'll know that some exile Iranians are a bit like exile Cubans. Like the latter, they have plenty of legitimate things to be angry about, but that doesn't mean they aren't, a good deal of them, batshit crazy. Lots of them support the son of the CIA-supported dictator who was so bad he landed Iran with their theocrats in the first place. Some of them are supporters of MEK, a goddamn case study in political cults.

Yes, but that doesn't mean they're not right. US and particularly Israel outright took credit for it, to a degree you'd be hard pressed to find any time in history. It wasn't just a spontaneous uprising, it was also very openly a foreign sponsored regime change operation.
Which doesn't mean they're aren't a lot of innocent people who have wanted to get rid of the theocrats all along getting murdered. I'm sure there are.
There are just enough in the opposition who have decided to ally with Israel (which would rather see Iran a Somalia-style failed state before a free and democratic Iran) and the dictator's sonthat any kind of moral legitimacy the movement could have had is out the window.
