Actually Americans, before the Obama Apocalypse, were the least racist people in the world. That is because we have been the melting pot of the world. Thousands of people from every nation on the planet have emigrated to America. Many were escaping racism, religious persecution and political imprisonment. No other nation on the planet is as racially mixed, in total absolute numbers, as the US. However statistically, the racial mixture does increase the number of racist incidents. Since the left often refers to Muslims as a race - note that you do not see incidents of Muslim racism in Japan, because they are not allowed to immigrate in the first place. Japan is full of Japanese. Asians. Almost no blacks. Look at Mexico. Full of Spanish Americans. Very few blacks. If the US has been strongly racist against blacks the past few decades, why haven't blacks simply moved to Mexico ? Just a short bus ride.
So how long until we see the first black Mexican President ? The first black Japanese leader ?
There are approximately 100,000 muzzies in Japan. Of those, 10% are Japanese converts. Most of the balance are immigrants. The Japanese govt got in trouble back a while for monitoring some mosques. They also have quite a few as teachers of Arabic etc. so the Govt can translate muzzie propaganda.
