There's also his current strategy, point out tha libertarians can't be racist (blacks can't be racists either, arabs can't be antisemites), and continue to point out that when he pardons all non-violent drug criminals, that will help blacks. I can't believe he included that in his denial.
That was pretty amazing.
I think he is trying to say that he promotes individual rights, which is the antithesis of collectivism. Collectivism is about putting people into groups, and recognizing rights as being apart of that group. Rand said “Racism is the lowest, most crudely primitive form of collectivism. It is the notion of ascribing moral, social or political significance to a man’s genetic lineage . . . . Which means, in practice, that a man is to be judged not by his own character and actions, but by characteristics and actions of a collective of ancestors.”
That is what he means when he says libertarians can’t be racist.
