Why do we fixate on the idea that only Americans are racists?
Racism is endemic the world around. Ask the Gypsies, Ask the Kurds. Ask the Armenians. Ask in Bosnia. Ask in South Africa. Everywhere there are people there are those who want no part of those who are different from themselves and are willing to use any means to prevent contact.
As for America. It has improved over the last 50 years but racism will never be totally irradicated. Let me tell you though that Jews can be very racist. Blacks can be very racist. Orientals can be racist. Anyone in this country can be a racist. Please note that I say "can be" not "is".
I've done a little traveling in my time and I find it present in every part of the world I have seen.
