I'm not sure your observation of of "white trash", "redneck", and "trailer rats" not suffering from systemic racial discrimination is an accurate one. I for one can assure you that people know how to suss out the difference and it starts at a young age.

It's not clear to me what you're saying. Unless I'm misunderstanding you, "redneck" isn't a racial group.

No-one is arguing that class-based discrimination doesn't exist, as it certainly does.
