Hmmm. Redneck is a perfectly acceptable word in the PC world, because it can only refer to whites. Whites are a non-protected non-minority who are responsible for all racism. On the other hand, "Gurley" sounds like "Girly", which raises issues of sexism and Homophobia™. As we all know, words that sound like banned words are also banned, but only when used by whites. So, if a black teacher used this phrase, he/she would probably get a raise.
Now we're making perfect sense of it all. ;-)
I would think this will all be sorted out when Mary Francis Berry, jj, crazy Al and Queeesi converge on Huntsville in the very near future.
