It would seem to me white folks who might get called rednecks are of two types: those who would wear it as a badge of pride and those who wouldn't because they feel offended at its implications.

No reason for the 1st group to mind it being thrown around.

As for the 2nd, tho they might be offended at having this stuff implied about themselves, are they gonna deny that there really is folks it applies to? If so, they're crazy. If not, why should they mind people using the term?
