I don't why some people do so much propaganda that Pakistanis are so religious due to policies of Zia ul haq etc but I can't find any religious person here in my neighborhood most of people are what would be considered athesists you can say they are Muslims only culturally and they hardly ever think about islam or being Muslim for them being Muslim is just cultural thing but pashtuns are not like Punjabis they are religious
There is no difference in ignorance when it comes to Pashtuns or Punjabis. Infact the pashtuns are even worse in some forms of ignorance than the punjabis and I'm not assuming or guessing here but speaking from personal experience and from knowing people with vast experience of being pashtun and living amongst them.
All are ignorant in their own ways and actual religious practice and knowledge is limited to the very few who actually go and study and make it a part of their lives out of the fear of the here after.
You say 90%, I'll even say 99% are ignorant on one level or another when it comes to Islam and never cared for doing any research or enlightening themselves with the wisdom of God.

“And they will say: O our Sustainer! Behold, we paid heed to our leaders and our great men, and it is they who have led us astray from the right path”
Zia ul Haq did not bring Islam to the country. He only brought an extremist concept of Religion, which was to practice and follow religion while being extremely ignorant about it. Just like what Wahabism was brought to kill actual Islam amongst arabs.
Today I was visiting a markaz, and there was a woman coming with 2 other guys (co-workers I presume). And right beside me were 2 taxi drivers. I kid you not, he said "Woh dekh shera kaun aya hai....", and then they proceeded to stare her to kingdom come.
What did you do about it? Did you call them out on it or tried to reason with them?
It all starts and ends with how we deal with it at the individual level. The state or society can't do anything about it collectively just yet nor there is any will to do anything.
