My sincere apologies if this offended anyone. What would be an appropriate term in this context? Edit: I'm not a native speaker and have heard this term in use in the media to the point where I did not believe it to be a "racial slur" as wikipedia says it is. So, say I want, for instance, to represent the stereotype person who rolls coal on their diesel pickup and believes global warming is a left-wing conspiracy. Look it up on youtube if you don't know what rolling coal is. (We can get into a whole debate on whether stereotypes are inherently good or bad, but that's not the point. They're a very effective commumication tool, which is why humans are so quick to label and group other humans, but obviously they're only to be used when not offensive.)
