True - our “N....rs” are called “white trash” or “trailer trash”.

"Crackers." My understanding is the origin of that slur is derived from 18th century slave traders that used whip-cracks to drive slaves.

No. They cracked whips overhead when driving cattle through palmetto scrub.

There’s a key difference between being called ‘white trash” vs “cracker”.

White trash is used by white people to refer to the lowest class of whites, whereas “cracker” is used by blacks as an insult to ALL whites.

There’s this other possible origin of the word cracker that I find more believable...

“Another possibility, which may be a modern folk etymology, supposes that the term derives from “soda cracker”, a type of light wheat biscuit which dates in the Southern US to at least the Civil War.[23] The idea has possibly been influenced by “whitebread”, a similar term for white people. “Soda cracker” and even “white soda cracker” have become extended versions of “cracker” as an epithet.[24]”
