There are a lot of polarized nations in the world but honestly I always felt Iranians to be the most complicated and I hope Pakistanis are reading what I have to say because we are not as bad as we think.
Where do I start?
Politically, Shah regime extreme left and Khomeini / Revolutionary Guards extreme right. Both failures. The common traits if any is that they were/are corrupt to core.
Socially, Iranian people on two opposite spectrums. The people who are anti islamic are not only pro west / traitors but also Atheists, They view Islam as an Arab religion although historically speaking, the Persians have made a bigger contribution to the islamic world culturally and scientifically than others. How can you neglect that? The religious on the other hand are fundamentalists, imo, worst than wahbbis. Their policies are unrealistic, terrorising and causing the country to be isolated in the world.
Some people correlate these traits with Turks but honestly, no. I get the fundamental differences between Secular Turks and Turks who want to revive Ottoman glory. However, despite their differences they stand united for national interests. They have no issues getting along with each other. You will find a girl wearing a hijab holding hands with a girl in mini skirts.
That's an interesting take, but, I'd argue that their foreign policy is one of the best in the world if you look at it from the perspective of not wanting to be a slave to others. And, due to that, they are facing massive backlash and isolation.
And I also agree with your Turkish Kemalist equation. Kemalist and pro-Islam Turks have huge differences, but both sides stand for their own national interests. That's what keeps Turkey's ambitions alive.
In Iran, anti-government Iranians are:
1.) incredibly anti-Islam. And, not in the way the Kemalist Turks are. They hate Islam to the core and would do anything to get rid of it. Kemalist Turks call themselves Muslims (which is a good thing) and wouldn't have that much problem doing things for the benefit of Islam knowingly. They are just confused people in regard to what Islam is about. Iranian are confused about Islam to some extent, but
2.) the anti-government Iranians make sure they bring down their state and national policies with them. They have no understanding of how the western world views Iran and wants to bring it down. If it weren't for the 1979 Iranian revolution, Iran would be the worst country in the Middle East and perhaps the world right now. They would be a huge client state that makes the current Pakistani army look modest in comparison.
And, I also agree that Pakistanis are not as bad as we make ourselves out to be. We, like the Turks, have huge nationalism that keeps our country alive. But, at the same time, unlike the secular anti-government Iranians and secular Kemalist Turks, even the more secular Pakistanis understand the importance of Islam. There's a reason that Pakistan was built under the name of Islam.
