2. Originally from the sound of a slave master's whip. Has been used to identify oppressive, racist, ignorant, whites.
Whites who feel threatened by these oppressed and disadvantaged people will say that a black person calling a white person "cracker" or "honkey" is the same as a white person calling a black person "nigger." While the derogatory implications are similar, only "nigger" has been used by a people of power to enslave, victimize, rape, inprison, and institutionally oppress blacks. "Cracker" does not have this history.
There is no such thing as a "Jolly Cracker Bank" for young black children to save their allowance in. Search ebay and you can find a "Jolly Nigger Bank" for your white kids.
A "cracker" is someone who holds the whip to beat his slaves. A "nigger" is the abused slave.
No one is fuckin better than anyone they are equal, until your actions or reputation lowers your social status and respect, of course.
