So they're more concerned about something that was dissolved in 1979 more than the backward theocratic death cult in charge today? aGrEe tO dIsAgReE?

Yes. Iran did have a democratically-elected Prime Minister before they were removed in a joint US-Israeli coup d'état. Iranians are perfectly justified in viewing America as the enemy of democratic reform. They are also justified in their worry over Israel installing a worse theocratic death cult, as I argued above.
