I dont know why people are getting offended with such statements unless they are Pakistani pashtun or baloch. There is no single Indian look( look at people of Jammu and Kashmir Haryana, Delhi and Himachal Pradesh, Ladkh. and compare them with people from South India and north east India ) . There is no single Pakistani look( Kashmir, Photohari, Central Punjba, Sindh, Baloch, chitrali, Hindko, Pashtun). There is so signle Indian language(Punjabi,Hindi, Sindhi Urdu, bengali, Marathi, Telgue, Gujrati, Malyalam, kannadaa) . There is no single Pakistani language( Punjabi, Pahsto, Sindhi, Balochi,Urdu etc) . There are speakers of Kashmiri, Punjabi and Sindhi on both sides although the dialect have been different. There is no single Indian food and there is no single Pakistani food.
There are some similarties between two same ethnic groups and tribes whther they reside in Pakistan, India Afghanistan. Changing religion dont change your tribes and ancestry though religion influence your culture and lifestyle to great extent . We also had migration of people from boht countries after partition. Its funny that some of us try hard to portray daleep kumar, sunil dutt, Khans, kapoor family as someone who had origin in Pakistani aka Pakistani yet here we are fighting over some similiarties and differnces ..
