From Charles’ update:

Curious, isn’t it, that Breitbart’s readers don’t report those vile racist comments?

As a matter of fact, IntenseDebate also allows rating comments — and the ugliest remarks on Andrew Breitbart’s websites often have the highest positive ratings.

And that’s the essence of the matter: The problem is not accidental or incidental. The racism is not isolated, it is systemic. It is what is cultivated at Breitbart’s online empire of bigotry.
