What utter and complete horse manure. Unless one expands one’s definition of “whites” to include blacks, browns, yellows and reds.
Because all HUMANS are “bigots” - in the sense that everyone makes snap judgements at some time about some people based on some sort of group characteristics.
This “bigotry” is also known as “judgement.”
And one's own actions is usually they reason they fall under judgment. Of course, those who find themselves blameless wouldn't understand this concept. It would go right over their heads.
