The Hindi muslims were like those from UP, Bihar, Hyderabad, Bengal, Punjab , Sindh, Kashmir etc.........Pashtuns/Afghans and Balochs were not Hindi/Indic muslims so how they ended up in Pakistan if it was for Hindi muslims?.... and if it was/is for Hindi musalman, why doors for citizenship are not opened for 20 crore muslims of india?
Keep in mind that "A" in Pakistan stands for Afghania so unintentionally it is partly Afghanic which is synonymous to Pashtunic. So Pakistan is not a country of just Indian muslims , only two of its provinces can be called "indic" whose people themselves are running away from "Hindi" tag
That being said the "Bar Afghans" have their own country Afghanistan, Pakistan is not their country, it can never be their country but they have strong ties with Pashtun portion of Pakistan which can not be severed.
