Bashing the criminal founder and his "principles" is not "black bashing." If some white dude with a similar (criminal/Marxist) background invented a new religion that was getting this much press I assure you the criticism around here would be just as enthusiastic. ....perhaps even moreso.
"Conservatives love David Horowitz."
Horowitz is a former Marxist who's now a conservative. ....not exactly the equivalent of Karenga (to understate the matter).
"If a person does celebrate it, it is their business."
Never stated or suggested otherwise.
Strom Thurmand was a segregationist who never renounced his segregationist past. How much hell has he caught on these boards?
