This is preposterously pseudoscientific. Even the dumbest person has a basic a grasp of equivocity. The inability to do so suggests mental illness.
The same person who uses the word "blacklist" is very much capable of preferring the elegance of a black suit or the sleek beauty of a black sports cars or a dark pair of slacks, and dislike white suits and white sports cars or white jeans. He may prefer brunettes over blondes.
According to this reasoning, "Enlightenment" should also be renamed, as the association of "light" with good and "darkness" with evil "exclusives people" (I, too, would rename the Enlightenment, but for much more substantive reasons).
It is insane to think that the use of words like "whitelist" and "blacklist" somehow "excludes" anyone.
