[The psychosocial roots of racism and xenophobia].

The concept of race is only a human particularity. In spite of this, the racism, as a construction of imagination or a paranocial delusion or an ethnic attitude, is spread among the narcissist personalities and the environment dominated by nationalist or religious fanaticism and anyway generates collective violence. There is also a psychosocial racism almost always actual in the common human relations, appeared in form of positive attitudes towards similar others and negative attitudes towards different others. The best defence against these both phenomena are the attitudes of tolerance, understanding and liking.
