Its rather clear.Why do Pakistanis want to convert everyone to Islam ? I ve seen people talking here of India converting to Islam as well. Now Europe too. Why can't you guys just celebrate the diversity of the world. Diversity is good.
Pakistanis have not really achieved anything that they can be proud of. So they take mental refuge in the larger Islamic identity. Therefore the only way they can continue to 'win' or have 'achievements' in that space is people converting. This is why you will rarely find Pakistan taking the lead or achieving anything in fields of science, maths. This is reflected in the society.
