In China you can purchase products colored in "n Black" and children are taught in schools (when studying foreign countries) that black people are lazy, stupid criminals while white people are intelligent and hard-working. Japanese people still largely see themselves as the master race, and they allow almost no immigration lest their blood be tainted. Many people in India, Pakistan, and within Central Asia are pretty much genocidal to other tribes/religions, as is also the case in Southeast Asia, and Russia of course isn't all that nice either. So, obviously, Asia.
India and Pakistan as well have seen less violence and genocide than Europe has in it's past. Just sayin'.
And anyways when did religious bigotry (be it Hindu vs Muslim or Shia vs Sunni) become racism?
I voted for the Middle east, of course. Europe is a contender too.
