And it's laughable that you talk about defamation of character when this thread is about a direct, in context quote.
You're equating a stupid, disgusting racial slur that goes to the idea that a certain shade of color is not entitled to justly embrace a political ideology with a sentiment that merely eschews a system of thought and its adherents. The former is racism. The latter is the free asociation of ideological dissent!
But then that has always been lefty's wont, i.e., to disregard such distinctions.
