Iran in the 1970's was probably more socially liberal than Spain, Portugal, Ireland, Greece etc.
In the countryside, or in the working class neighborhoods of Tehran, Isfahan, Mashhad, or Tabriz? Probably not? Amongst the upper and middle classes? Perhaps. The key difference of an dedicated progressive and secularising regime in Iran versus decidedly traditionalist governments in the aforementioned countries does add credence to your point.

Interesting. Do you have a source?
There are many YouTube videos that try and show what Iran was like "before the Revolution". Of course, these present an idealised picture that ignore what things were like for much of the population, but they have their merits.
