Rora, what about Sindhis ?
By the way I'm not sure if there is anything called as 'mainstream Pakistani culture' ! If you move to Balochistan they have their own culture, the Pukhtoons with their Pashtunwali, the Punjabis with their own even the Sarikis & the Hindkowans have a different culture then ours, the Sindhis definitely have that ! And yet because we've interacted with each other for so long & been living in each others traditionally thought off areas, we've have certain cultural practices which overlap with each others.
And I will never forgive you for bringing Bilor to power ! Kameenei ne mujheee 4 ghantiii railway station pe wait karvayaaa thaaa !
