It's time to talk about it.
And about the fact that the Democrat Party's militant wing was the white-supremacist Ku Klux Klan.
Why would Martin Luther King, Jr. have supported the Democrats, who were responsible for the KKK? It doesn't make sense.
FYI you may explore this page of the National Black Republican Association. Plenty of links, including an article by MLK's niece, who confirms her uncle was a Republican, and who also reminds us that the Democrat Party is "the party of the Ku Klux Klan". Here's a good video page.
Of course, this isn't something that the Old Media wants to discuss. They don't want to anger their Prophet Obama, who's apparently in denial about the horrible racist truth about the Democrat Party.
