I will try to answer in Airboss's style
Hindi is not my mother tongue. I learned it only recently and partly. With my limited vocabulary I could understand Zaid Hamid's speeches, his side kick's questions and some videos posted here. Now how did that happen?
If you complain about Indians not being similar to Pakistanis, the inevitable question is which Indians are you comparing yourself with?
And Omar here argues that only 3%(another he place I think he mentioned 5%) Indians are similar to Pakistanis so the people are different.
Well if you don't know 3% match in India is a huge thing dude!!
Your idea of dark Indians is true with South Indians ans some North Indian populations which can be differentiated by their caste or tribe easily.
People in the North think all south Indian languages are same or similar. That is only partly true. Many people of one of the four prominent south Indian languages cannot understand a bit of any other language of the group. Also the darkness kind of decreases on an average as you go up. So you can consider these people as different populations.
Like wise you can differentiate between smaller and smaller groups in India and end up nowhere. With regard to this you do agree that there is some similarity between Indian and Pakistani Punjabis. And cultures are not watertight, so it naturally extends the pattern in India to the North West.
If you want to disagree with this just on the grounds that you want to be a 'proud Pakistani', I should point out that you need not.
