Why call such people reverse anything. Why use the language of the left? A racists is a racist is a racists, not a reverse anything. So if you want to say white supporters of Obama due to guilt are “Uncle Toms” call them such. Again why use the language the left oks.
Because sound bites and bumper stickers reach more people. By definition, these "White-Guilters" ARE racist; but the catchphrase is better for marketing.
