Could be.
But people in the west are usually pretty straight forward on their likes and dislikes.
True, but when it comes to sensitive matters like multiculturalism and racism they are very cautious. They are badgered with pro multicult propoganda, so on surface they are bound to be more politically correct.
It would be interesting to analyse the survey data though. As in city/group where the survey was undertaken. For example in Australia, the survey was conducted at the top university(ANU) of Australia. The survey population there and the population living in say low income suburbs would have different opinions sure.
