…"in things racial we have always been and continue to be, in too many ways, essentially a nation of cowards." No, Eric Holder: it is in things politically correct (notably, but not only, radical Islam) that too many of us are browbeaten by the PC police — at least, they do their best to try doing so — into becoming a nation of cowards.
You got it wrong, Mr. Holder; it is not "we average Americans [who] simply do not talk enough with each other about race." It is — certainly in this day and age — we average Americans who do not talk enough with each other about radical Islam.
In fact, I would add that at times it seems perhaps less true that "to get to the heart of this country one must examine its racial soul" than that to get to the heart of this country one must examine its political correctness as well as the fairy tales its liberal components.
…"if we are to make progress in this area we must feel comfortable enough with one another, and tolerant enough of each other, to have frank conversations about the racial matters that continue to divide us." Mr. Holder, frank conversations about radical Islam — whether it continues to divide us or not (it really shouldn't) — is what we need to feel comfortable enough with one another, and tolerant enough of each other, to do.
Update — Real Clear Politics says the same thing:
Who's the Coward Now, Mr. Holder?
