Lucky..Always good to try and understand how words change from culture to culture.
I think the difference between rednecks and yuppies- Yuppies are equally intolerant, but just more economically, upwardly mobile. Whereas, rednecks use Saturday night specials, yuppies weaponry is more upscale S&G Magnum series. Rednecks consume too much Budweiser, whereas Yuppies can be pickeled on Chardonnay.
I know yuppies can come in a more tolerant breed, but soccer moms, cell phones, and SUV's cause me concern from the perspective of a commuting cyclist in the commuter lane.
