Why is the "N" word against blacks bleeped out during radio shows but the "C" word against whites isn't?

It took me awhile to realize the"C" word was cracker. I thought it was conservative.

Depends on which N word and which C word we are talking about, because I have gotten into many an argument trying to explain to people that Negro and Caucasian are 2 sides of the same coin in that both are words originally designed to categorize your ancestry.
