I think being more religiously inclined is fine, as long as you tolerate others’ beliefs. Certainly more ‘expression’ of religious beliefs in Karachi but that doesn’t make it religiously intolerant or liberal society. I think Karachi does well in terms of co-existence of people from different beliefs (although the city somehow got cleansed of its big Parsi community and despite a JI being a substantive political force there).
I wouldn’t call Karachi ‘liberal’ as claimed in the piece by NFP, just because of the intolerance people there have for different ethnic and linguistic groups.
