..... the debate needs to be why extremism is bad, not why Arabism is bad. ....
There should be no "Holy cow" when discussing cultures. Otherwise it will be same as "Idol worshiping".
One should be able to discuss BOTH extremism, and Arabism without any fear of getting punished for blasphemy or such.
1400 years ago, Arab culture was not the epitome of niceness. However Mohammad pbuh brought some semblance of civilization to it.
We all know that Arabs tried to revert back to their old ways even during the time of Mohammad pbuh.
Such efforts continued and within 100 years or so, Arabs of modern day SA were able to successfully kick out the remnants of the changes minus some stuff like not putting pagan idols back in Kaaba.
The dark ages in the modern day Saudi have been around for 1300 years. No scientific or philosophic thought has come out of this black-hole (astronomically speaking).
Yes there was the tribal revolution led by Ibn Wahab etc. But ordinary Saudi has lived pretty much the same as they did 1000s of years ago. No sign of architecture, no Taj, no new buildings etc with the exception of Haramain Sharifan. Even those buildings were updated mainly by Turks.
Ordinary Arabs lived on the dole out of Hajis or simply looting the Haj caravans.
Situation only changed when thanks to USA technology, oil was discovered and from then onwards Saudis have done stop-gap copy of the Western culture. However their science, tech, and economic models are still stuck in a time that existed 100+ years ago.
However Pakistan's natives have done much better job in copying Western culture compared to Saudis for many many reasons.
Thus for Pakistanis to state that we copy Arabic culture is like a trip backwards. Our issues are much more urban than most Saudis could ever imagine. Those poor folks will take another 50-100 years to reach Pakistani culture of today.
Few Pakistanis go for Hujj Umra and think they understand Arabism. This is absolutely wrong. You gotta study Arabs living in small tribes away from big cities and away from Makkah Madina Jaddah. Then you will understand that anyone in Pakistan saying Arabic culture is "Islamic culture" is severely mistaken.
Quran Hadees can be in Arabic, and few scholars who need to interpret it can easily pick up that language.
For the rest of ordinary citizens of Pak or even Arabs, there is no way to become Quranic scholars. We all do specialized jobs these days. And there is no way we can live off of Qirat 24/7 365 days.
Arabic language is not a guarantee of Quranic understanding. Just look at 350 million Arabs. Majority of them cannot understand Quran either. Why else would they be divided into so much firqas and fitnas.
Heck even the 4 Imams of Sunnis and 12 or 6 Imams of Shias could not agree on single interpretation.
You expect 200 million Pakistanis to learn Arab to learn Quran, and I tell you, we'll have 200 million sects.
Peace.
