Ethnic prejudice

Racial bigotry
Passive racial discrimination

Ethnic hatred, inter-ethnic hatred, racial hatred, or ethnic tension refers to notions and acts of prejudice and hostility towards an ethnic group in varying degrees.

There are multiple origins for ethnic hatred and the resulting ethnic conflicts. In some societies it is rooted in tribalism, while in others it originates from a history of non-peaceful co-existence and the resulting actual disputed issues. In many countries incitement to ethnic or racial hatred is a criminal offense. Often ethnic conflict is stoked by nationalist fervor and sentiments of national superiority—for which reason inter-ethnic hatred borders with racism, and often the two terms get conflated.

Ethnic hatred has often been exploited and even fueled by various political leaders to serve their agenda of seeking to consolidate power or make electoral gains by calling for a united front against a common enemy (real or imaginary).

An example for ethnic hatred is the reported animosity toward the Romani people in Europe. The Romani people, also known as Gypsies are one of the marginalized and persecuted ethnic groups in Europe.

When you call yourself an Indian or a Muslim or a Christian or a European, or anything else, you are being violent. Do you see why it is violent? Because you are separating yourself from the rest of mankind. When you separate yourself by belief, by nationality, by tradition, it breeds violence. So a man who is seeking to understand violence does not belong to any country, to any religion, to any political party or partial system; he is concerned with the total understanding of mankind. (J Krishnamurti).
