Does the word 'cracker' carry with it the history of centuries of violence, oppression, slavery, and murder?

Is it a double standard, or are the words just not equal in meaning?

They not be equal in meaning, but they are both still racial slurs. Should some racial slurs be acceptable and other not? Which are and which aren't? How do we decide?

Neither are generally "acceptable" in polite discourse, but to say one isn't clearly worse than the other is silly. Does someone really need to "decide?"

*ss and c*nt are both rude terms for body parts, but I'll use only one of them in front of my mother.
