Turkey is not a good argument for Islam being "tolerant" or Muslims being somehow naturally "less religious."
Ataturk abolished the Caliphate in 1924. He explicitly introduced the constitution to Turkey which declared the state to be secular, that is, independent of any religious influence! He effectively banned headscarves (hijabs, nijabs, whatever) in all public institutions (being religious attire, therefore to be separated from state), including schools and universities.
The West however wasn't so smart recently, forgetting how much fights and sacrifices were needed to achieve the freedoms we have now (but will we keep them depends on our readiness to stand for them, more than up to now).
Erdogan now pulls Turkey back to the pre-20th century state. And unfortunately, there are enough of those who support him and his Islamic "revival."

The comics Persepolis that you mention, among some personal stories, also covers the moment of "Islamic revolution" in Iran, which, among many other things, destroyed women freedoms. Before:
