Not quite. The results of the study are not surprising, if one keeps in mind that the survey was about tolerance towards other races. Race does not play a major role in most Pakistanis' psyche.
In fact, if the question remained the same but was geared towards cast, religion, politics, or pretty much anything else, I'd wager that the results would still largely remain the same. We are pretty tolerant when it comes to letting people live or be where they want to be.
A sturdier question geared towards religion, however, would be a completely different story. Say, "would you let an Ahmadi be appointed as an advisor to the government?", "Should Pakistani Hindus be allowed to build new temples in the country?", "Should non-Muslims be allowed to preach their religion in the country?", etc.
PS: We are not a PC nation.
