EDITORIAL OPINION This is obviously a high-voltage area to get into, but for what it's worth, John Ziegler does not appear to be a racist as "racist" is generally understood. What he is is more like very, very insensitive—although Mr. Z. himself would despise that description, if only because "insensitive" is now such a PC shibboleth. Actually, though, it is in the very passion of his objection to terms like "insensitive," "racist," and "the N-word" that his real problem lies. Like many other post-Limbaugh hosts, John Ziegler seems unable to differentiate between (1) cowardly, hypocritical acquiescence to the tyranny of Political Correctness and (2) judicious, compassionate caution about using words that cause pain to large groups of human beings, especially when there are several less upsetting words that can be used. Even though there is plenty of stuff for reasonable people to dislike about Political Correctness as a dogma, there is also something creepy about the brutal, self-righteous glee with which Mr. Z. and other conservative hosts defy all PC conventions. If it causes you real pain to hear or see something, and I make it a point to inflict that thing on you merely because I object to your reasons for finding it painful, then there's something wrong with my sense of proportion, or my recognition of your basic humanity, or both.
