Let me clarify. When I said that most Americans don't differentiate between Pakistani, Indian, and Arabic, I meant that when someone post something bad about one of those groups in America, they really saying it about everybody here.
Here's a example. When someone from America says how Indians are so stupid and then someone from Pakistan says how Americans dislike/hate Indians, they forget that Indians and Pakistanis are viewed as one people, and the American might just be saying it about mostly Pakistanis.
As for Pakistanis and Indians being the same, I don't think any two human beings are the same. They are some differences but the similarities do outweigh them. I just think the people should get along. We need to be able to differentiate between the government and the people. Most people don't want war or conflict. The government forces it on them.
The reason that most Americans don't differentiate between the people is because they are so far away and distinct from us. Kind of how like pretty much no body is able to differentiate between a Kenyan and a Nigerian in Pak/India.
