Absurd, ludicrous and laughable logic to say the least!
India is the bigger country out of two it has many sub-cultures and ethnicities. Indic population (Punjabis, Sindhis, Kashmiris and Mohajirs) are about 80% population of Pakistan. Heck, India even has sizable Pashtun population, whom we call 'Pathans'.
'Pakistan = A home for Indian Muslims where Muslims would be in majority' that was motto of Muslim league and Jinnah. You guys and your identity crisis. Arabs/Persians/Afghans must be laughing their heads off!
Only Pashtuns and Balochis can claim Iranian heritage rest of the Pakistanis are Indo-Aryans linguistically and ethnically but then again so are 80% of Indians. But Pashtuns have their own distinctive culture and identity. They don't need to pose as Arabs or Turks or whatever.
Let's just say the words 'India', 'Hindustan' or 'Bharat' have existed for thousands of years but the first time ANYONE in this WHOLE WORLD ever heard the word 'Pakistan' was not before 1940s. See the difference?
