Colour Prejudice
The path of least resistance and least trouble is a mental rut already made. We think it requires troublesome work to undertake the dashing of old beliefs. Self-conceit often regards it as a sign of weakness to admit that a belief to which we have once committed ourselves is wrong.
We get so identified with an idea that it is literally a "pet" notion and we rise to its defense and stop our eyes and ears to anything different....... (for example) the historically incorrect white dieties like the white Jesus.
