Pakistanis are basically delusional. They now try to insist that they are not Indian at all but the descendents of Arabs who came to India — the Arabs of course laugh at this and at them. They also, quite contradictorily try to say that they are “pure” Aryans, while Indians are descendents of Dravidians (and completely forgetting that Dravidians ARE Caucasians). Pakis are brain-dead idiots — the disease causing the vacuum between their ears is islam.
Because the big transfer of people called The Partition you find everybody you find in India in Pakistan, and everybody you find in Pakistan in India.
More anciently they were all pretty much the same thing.
