White persons (European) or individuals of any other ethnic group are not inherently racist or ethnist. Rather, as others have indicated, such negative behavior is learned - transmitted from adults to children, from older generations to the next.
My father worked for the World Council of Churches for a few years, and my parents entertained people from all over the world. I was accustomed to seeing people from Africa, Asia and SE Asia, as well as European. My parents also taught me that all peoples are equal.
I am an expatriated Aussie living in the US. I came with my family to US, and lived not to far from Evo, in the mid 60's and 70's. That was a time of turmoil in the US concerning the civil rights of minorities, and 1968 was tumultous year with the assassination of Martin Luther King and Robert Kennedy, the Chicago riots during the democratic convention, and the open racism across the US. Adding to that was the Vietnam war and the anti-war movement, as well as various counter-culture movements.
I had several friends of African-American (black), Hispanic (brown) and Asian (color?) descent, as well as European. It would have been strange for me not to. On the other hand, as I matured, I learned that not everyone felt that way, and I also came to realize that US society was heavily segregated.
During one summer in the 1970's, I worked at an oil refinery for a summer job. The personnel were integrated, but during breaks and lunch, the white males went upstairs to socialize, the black males went downstairs, the women and others (generally older) congregated on the main floor. I was amazed. I drifted among the groups, but spent most of my time downstairs. In the evening everyone left for home, and the blacks would generally go to a predominantly black neighborhood, whites to white neighborhoods, hispanics to hispanic neighborhoods, and so on. That is the way it was, and still is in many parts of the US.
I got to know most of the people with whom I worked. At the end of the summer, I left to return to university. I went to say good-bye to my new black friends, and to thank them for sharing their time with me. One, with whom I have been particularly close during the summer, said to me, "You're not like other white people." I was very sad, and not surprised, to hear that.
Racism, ethnism, nationalism, chauvinism, etc are still part of humanity today. It's not just whites, it is every ethnic or racial group. I would hope that humanity would now be making greater and faster progress to overcome what is effectively a continuation of tribalism and clanism. We still have a long way to go.
