Bigotry tends to involve underlying issues of fear, self-esteem levels, anger, and low levels of EQ. Note: Think of self-esteem issues as a circular continuum: abysmally low on the bottom; over-inflated on the top. Some individuals are stuck at one position; others flip-flop back and forth between the two positions.
Studies have shown that babies and children who are exposed to people of many different cultures early in childhood likely to exhibit bigotry behaviors--UNLESS the families and cultures teach it to them. Similar research has shown that babes and children who are exposed ONLY to their own culture’s music are less able to understand and/or appreciate the music of other cultures in adulthood.
