That’s quite the claim. Do you have any examples?

"The left", i.e socialists, communists, anarchists, etc, are supportive of a theocratic dictatorship? Not sure whats more unlikely here, a unified "left" or that they'd be unified behind a dictatorship with fascist principles.

Are these really left and right issues?

IE as the right is becoming more anti-Israel, you find a lot more pro Islamic Republic stuff there these days. The boomer and zoomer right are very different beasts.

I don't follow the left as closely these days, but imagine there are a myriad of opinions on the matter.

No, no we don't. Nor do we want to get involved in a civil war in Middle East on behalf of Trumps, Saudis, and Israelis.
