Why? You want to ban a word from TV?
You can make the case that the government just shouldn't ban words on TV, but the government does engage in censorship. There should not be a double standard when it comes to different racial slurs. I'm sure the FCC would act more swiftly against a name like the "Washington Negroes".
Let's say the government bans all racist speech against blacks. Obviously, that's a violation of free speech. Would it then be preferable for the government to ban all racist speech against Hispanics? That would just be an even greater violation of free speech.
If we can agree that the government shouldn't be banning racist speech, then I don't see why it makes sense for the government to do so to an even greater extent. Imposing even more restrictions on speech in the name "fighting double standards" doesn't seem like a logical thing to do if you accept the premise that the government shouldn't be restricting this sort of speech to begin with.
