The fact that more than 90% of libertarians are White remains true.
It's relevant by simply being another aspect as to why the Libertarian Party will never be a player.
It mostly appeals to young, white, single, childless males.
This is a transition group .. and thus libertarianism is a transition "philosophy" .. which accounts for why it has never been nor ever will be a player.
I just thought you, being a libertarian, might want to comment on why you thought your ideology appeals so out-of-proportion to Whites and not to other races?
Since that appeal is obvious, it's relevant.
