The term in the US is specific to white people and therefore racist.

I can somewhat agree with this, but I don't think most white Americans are all that offended when they're called a hick, hillbilly or a redneck, being called white/trailer trash for example is much more offensive, and is definitely racist. I still don't think it's as "racist" as a black person being called a "nigger", that's probably the king of all racial slurs.

BTW, most of the rednecks I know are pretty nice guys, and i'm a bit of a redneck myself.
