Cracker is not racist.
Some (esp. blacks) think it applies to the whiteness of saltine crackers and intend it as a racist insult.
But “cracker” really applies to the cracking of cattle drovers’ whips. Those were the original “crackers.”

That's exactly right, Florida Cattle drovers herding Yellowhammers using dogs possibly riding Marsh Tackies. (Not to be confused with the Florida Cracker Horse, which was also likely).
