From Attorney General Eric Holder:

Though this nation has proudly thought of itself as an ethnic melting pot, in things racial we have always been and continue to be, in too many ways, essentially a nation of cowards. Though race related issues continue to occupy a significant portion of our political discussion, and though there remain many unresolved racial issues in this nation, we, average Americans, simply do not talk enough with each other about race. It is an issue we have never been at ease with and given our nation’s history this is in some ways understandable. And yet, 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.

The Korean said the same thing 2.5 years ago, and he has been doing his part.
