There's a lot of incorrect information here, but I prefer not to veer farther from our core disagreement by litigating details that seem tertiary (though I'm happy to discuss them in another thread or after we've resolved our core disagreement--it's an interesting topic).

You were originally arguing that the Islamic Republic isn't evil because the protestors deserved to be killed because Israel and the US claimed to have coordinated the protests. I don't see how you're getting from "Israel and the US claimed to have coordinated the protests" to "therefore Iran's mass murder was legitimate". Even if the tens of thousands figure is exaggerated by an order of magnitude, it would still make the Islamic Republic an evil regime. Even if Iranians who criticize the regime are "batshit crazy", even if the US and Israel organized the protests, even if the Shah was really worse than the Islamic Republic, none of that justifies murdering unarmed protestors by the thousands. My position is that mass murder is wrong even if the protestors held opinions I disagreed with.
