Jimmah was ignorant about Khomeini & Islam - in addition to having other agenda against the Shah. Since then I've heard/read some call Jimmah a "demented loser". Obama OTOH is well informed about Islam & Islamist movements, but goes along with them.
You're of course right about opposition by the clergy to Shah's White Revolution & the right to vote to Iranian women.
Although, I believe A main reason why many Iranian women (not necessarily commie or leftist) supported Khomeini's leadership against the Shah, was because that generation of Iranians never experienced Islamic Rule, and, more importantly, never understood what Islam is really all about.
For example & from personal experience, I don't recall reading anything bad or negative about Arab-Moslem invasion of Iran in history class in Iran, nor about the killings, raping & forcible conversion of my Zoroastrian ancestors or community right up to late/early 20th century in Iran. My older sister says the same. Islam was portrayed in a positive light.
What was represented as "Islam" in Iran during the Shah, wasn't real "Islam". It was somebody's idea of what Islam is or should be. In a way, I can appreciate why Islam was represented as such at the time in Iran. Equally and in hindsight, the misrepresentation of Islam back then did lot more harm than good. Because Islam, itself, has not been reformed in nearly 1400 yrs. And, it brought to Iran a set of Bedouin Arab culture, which has been fairly well embedded since then in Iran.
right up to late/early 20th century in Iran = late 19th/early 20th
