The term has been used to describe "an inextricable problem or situation," and I could understand you naming your dog because of that, but your explanation of the name seems linked to the dog's coloring. . . and in the past it was used as a racial slur for both African Americans and Maoris. If your naming of your dog has absolutely nothing to do with anything racial - although it has been used as a racial slur before - why did you mention the dog's coloring as though it was relevant to the discussion, and what is the reason for naming the dog that?
Commen sense would dictate that a thread discussing race would bear some relevance to the color of a dog named Tar Baby. And her dog is white so I'm not sure what your point is......if it was black ok, but it's not. So how did she link the color of her dog to it's name???
