The list of bad words grows:
niggardly
evacuee
tar baby
tar and feather
macaca
Some people can't help themselves. They open their mouths and advertise their ignorance.
BTW, people did get tarred and feathered in the past. But it wasn't in the south. It was in New England in the 17th century and the victims were white.
Also words that Ann Coulter used - but those don't really count because she refused to apologize.
