I don't need wiki to learn about it as my own family migrated. You have to keep in mind Urdu speaking people living in Karachi are not the only people who migrated.
Why don't you accept that Urdu Speaking people are also part of problem of today's situation. You people didn't tried to mixed up with native people to form new Pakistani nation.
Would you like to explain the bold part?
Yes they absolutely are.. but at the same time there are vested powers within the Native people that have disrupted the relative harmony that existed between the migrants to Pakistan and those that had gained freedom from their British masters.
Pakistan's basic problem is that we are not a nation at all..but a breeding ground for nations.
When you accuse one section of the population of traitorship .. you accuse Mohammad Ali Jinnah of being a daft idiot.
In that case.. lets break up Pakistan.. Balochistan can go.. Sindhustra can be formed.. Punjab can go back to Indian Punjab.. and Kp and do whatever they want.
because attitudes looking to create blame and conflict such as yours will eventually lead to this.
Sindh is the ancestral land of Sindhis they should be the ones to decide if they want to give their land for a muhajir province, public referendum should be held in Sindh where native sindhis can cast a vote in that referendum.
No one has any issues with any group living in any corner of Pakistan as equal but pushing a muhajir card without a province is not belonging is foolish, if you feel like that then you never really accepted the land as yours.
People can not demand to carve out pieces of others ancestral land, when they can live there as equal pakistani.
This is the basic issue.. What was nothing more than a land mafia problem has been turned into a ethnic political one.
And vested powers..
Those from Punjab, KP and Sindh.. along with dictator bred Fat cows like Altaf have turned tiny cracks in this nationhood into deep chasms...with bleating goats following hate blindly as their IQ allows only that.
As for the issue of so called Mohajirs..
The ones from Dehli and other areas came to Punjab as well..
Here they live with the population..and while the "urdu speaking" tag is still used by low level feudal types..
The integration has been fairly seamless.
