I’d like to discuss ancient Greek history. When the Greeks voted, they were given a white marble and a black marble. To signal an affirmative vote, a person placed a white marble in the clay jar. To vote against something, they dropped the black marble in the jar. This is the origin of our vocabulary words whitelist, blacklist and blackballing.
This is a case where the unidentified speaker claimed unconsious bias when none is present. To infer that these phrases show racial bias is to be ignorant of the facts of history. There is NOTHING racial about these phrases, except in the minds of overly sensitive people who *believe* there is a racial connotation.
The solution to this problem is education and I will be glad to have this conversation with anybody who challenges me over these phrases.
