You're right on the money. There isn't anything even the least bit racist about the song. It is a satire of liberal racism. It is insensitive. Insensitive to white guilt.
Apparently liberals aren't the only ones who suffer from that neurosis. Democrats count on that fear of being called racist, homophobic, war mongers and all the other labels to divide the GOP between conservatives and the squishy middle who are scared to death of being labeled something negative.
You guys are delusional. You would have to live under a rock not to know that Negro is not a word used in polite company. It is offensive to blacks and was meant to be offensive in this song. It’s too stupid for words.
