I don't think it would matter much to those who hate ZAB instinctively because of false propaganda. Allow me to give some personal account of the Karachi in the 70's.
ZAB has been accused of the so-called Islamization quite wrongly. Yes, nearing the 1976 elections, he did introduce some cosmetic 'Islamic' steps in order to blunt the onslaught of the Right-wing. Steps included making the Qadianis non-Muslims--it was regrettable but that was not Bhutto's personal choice nor his sole decision (read up Cowasjee--a confirmed ZAB hater--on that). ZAB did ban public gambling and drinking etc. But no where you will see he went much beyond that.
ZAB was as much an 'Islamist' as GWBush was a 'Christian'. No more, no less. Politicians.
The fact is the PTV shows then, the social landscape then, the public discourse then was never too much influenced by ZAB. He was publicly rediculed by Pakistan's press and whatever media then. A murder FIR was filed against him--serving PM of Pakistan then--which led to his hanging eventually. But the beaches of Karachi, the nightlight of Karachi, the social landscape of Karachi was not much touched by ZAB.
Even in 1979--about two years into Zia's rule--my school lady teachers used to dress in jeans and skirt. Up to that, carrying and killing by daggers ('Khunjar') was the norm.
Of course it all changed after that. The television shows changed. The way to greet and say goodbyes changed. And the way to kill changed as well.
So, Mr. ZAB haters, don't give us crap about him. If you had not lived through the ZAB days and the Zia days as relatively grown people then you freaking don't know crap! I have seen it all. In Karachi. My parents stood up against ZAB in 1977, only to regret it later when they saw what followed.
