Lol.........Punjabi Pakistanis have as much in common with bengalis as they do with Sub-Saharan Africans. That's the reality. It can be clearly seen. In fact the Pakistani Punjabis have far more on common with Iranians and Turks yet we are still not forming a nation with Iran or Turkey. Historical facts will also confirm that there was huge amount of interaction and interbreeding between the people of modern day Pakistan and Iranians, Turks and other Middle Eastern peoples. It also explains the physical traits of Pakistanis. We NEVER EVER shared this type of contact with bengalis or other groups east of us.
Your Punjabis are as Indic as our Pubjabis.
Inter-breeding doesn't a race make.
My post was about different races not being able to come together to form a nation.
