Yep. And, apparently they forgot which party freed the slaves in the first place. (Republican Party)
Not quite- BTW is well-known and well-respected among most Blacks and is one of the most frequently mentioned figures during Black History Month. His teachings were admired and emulated by more "radical" Blacks like Marcus Garvey, Elijah Muhammad, and Farrakhan.
Ultimately, what made BTW's teachings less successful among Blacks was White racism, which drove many Blacks into the DuBois/NAACP camp. It is fear of racism today that makes most Blacks leery of whoever they feel is racist. Changing that is a two-way street, and too many on the right wing seem to be reluctant to cross that street.
