No "politically correct" isn't correct, all it does is stifle conversations, conversations that we NEED to have. PC is used almost exclusive to prevent speech, generally but not always from white people. Is some of that speech uncomfortable? Yes, but is stopping said speech worst? I would contend, yes. Preventing someone from freely speaking their mind is far worst than said speech.
Being PC means you shut people up by calling them a racist, a homophobic, or whatever, FORCE them not say that "word". Gay, Queer, N* gger, etc. don't let them EVER say that word. Don't ever allow them to speak. Of course you won't change their mind and will just re-enforce their views. Especially if you ask is minority person X held to the SAME standard.
Having someone say what's really on their mind, and using reason to show how they are wrong, is far better than censoring their speech. When you censor people all you do then is drive them underground. You GIVE them power, "They don't want me to tell you this because it's not PC, but it's the truth." How do you counter that, you can't because you can't hold their speech up to the light of day. You can't counter what's not being said in public.
Michael Richards called two black hecklers the "n-word", was he provoked, yes should he have responded, probably not, after all it's probably wasn't the first time he was heckled, but what fallout did the hecklers receive none, but Richards career is virtually destroyed. While this was happening the hecklers didn't just want an apology, they wanted compensation too.
Now compare that to pass that given to Al Sharpton and his comments. “White folks was in the caves while we was building empires.“We built pyramids before Donald Trump even knew what architecture was…We taught philosophy and astrology and mathematics before Socrates and them Greek homos ever got around to it…" "Do some cracker come and tell you, ‘Well my mother and father blood go back to the Mayflower,’ you better hold your pocket. That ain’t nothing to be proud of, that means their forefathers was crooks.”
Now imagine any white person saying all blacks are crooks, what would be the fallout?
If we're going to be PC and not say the N-word, then we shouldn't allow the use of "White boy," "Cracker," "Honkey," "Whitey," "Caveman" etc. See it so easy to be offended, that soon you wouldn't be able to say anything negative about anyone or any groups true or not.
Remember if screaming "white power" is a racist statement doesn't that make screaming "black power" (after all some in the black power movement have said that black need to kill whitey) also a racist statement and if we're going to be PC should they BOTH be silenced?
