You make a valid point here but can you also deny this:
Punjabis (PPP supporters incl. many brainless* jiyalas* in Punjab) would not hesitate to vote for a Sindhi candidate or leader in favour of a Punjabi in an election but Sindhis would never vote for a Punjabi candidate in favour of a Sindhi - as confirmed by past elections! Hence I say Punjabis are THE most broad-minded race amongst Pakistanis. Sindhis can’t see beyond their own nose or Bhutto due to years of brainwashing
