It can only be a derogatory term, because the people suffering from this condition are bathed in hatred and incapable of rational thought.
Case in Point:
Last night, October 17, 2006, Takoma Park, MD campus of Montgomery College. I arrived at the campus in the early evening to attend a seminar related to my profession. I purposely parked my pretty-good-gas-mileage SUV back in to the parking space, because I have multiple conservative-type bumperstickers on the tailgate. I figured most people would walk through the wide and open parking lot rather than along the narrow sidewalk at the edge of the building where parked cars crowded the narrow space - for personal safety reasons if nothing else.
Anyway, I went inside and met old friends and colleagues as we settled in to learn about the latest technology in our field of study. It was an enjoyable and informative evening.
As I walked across the parking lot when the seminar ended, I saw something on my windshield, tucked under the wiper...
"Anti-American stickers?" What was this person talking about?
I went around to the back of my truck, to see if some errant lefty had stuck anti-American stickers on it without my knowledge...
Nope. All was well with my mobile conservative billboard. My "Semper Fi" and US Navy stickers were intact, as was my "9-11" pentagon shaped sticker. My "Gitmo" and NRA Life Member stickers were also untouched.
What then, did this anonymous messenger mean, that I should feel shame for so-called anti-American stickers?
What is anti-American about wanting our country's borders secured and Americans' rights upheld?
How else could any person in their right mind come to the conclusion that these stickers are anti-American?
Maybe the anonymous note writer is an elitist football fan who thinks Alabama is a foreign country?
To borrow from Tide fans...
We're gonna beat the Hell Outta you!
(figuratively speaking, of course)
