Once again, it's time to take up the challenge of Attorney General Eric Holder and prove that we are not a "nation of cowards" and afraid to hold an open, honest discussion about race.

In particular, the innate, pernicious, and corrosive racism of today's left. Here are three examples:

1) This year, there is exactly one black candidate running as a Democrat for the US Senate -- Alvin Greene of South Carolina. But is the national Democratic machine doing anything to help him win his race? Absolutely not. Is Barack Obama helping a brotha out? (OK, bad choice -- Obama won't even help out his own real half-brother, let alone a "brotha.")

No, Greene is getting no support whatever from his party. And it can't be because he's inarticulate, with no proven record of achievements, and currently accused of a serious crime -- none of those have been disqualifying factors to other Democrats in the past. The major difference here is that Greene, unlike Jack Murtha, Ted Kennedy, or a host of other Democrats I could cite, is black.

In other words, Democrats had no problems with fumbling, inarticulate do-nothings with shady backgrounds until it was a black man.

2) MSNBC. The left's favorite "news" network. Recently, they put up a promotional graphic featuring their lineup that was positively blinding in its whiteness. It was so bad, that they had to re-issue it to feature a black woman.

Talk about transparent tokenism. Tamron Hall is so important to MSNBC, they completely forgot about her the first time around. And, when they added her, they made sure that she was put in the dead center, her pink suit leaping out from the dark suits worn by the other, white staffers.

3) JournoList. The secret cabal of 400 leftist and left-leaning journalists, academics, and other soi-disant elites is finally crumbling, and the membership list is slowly emerging. So far, it's blindingly white. Of the 105 depicted so far, I see one Asian and two or three blacks. (I'm no expert on racial identification, as I see it as unimportant, and some of the photos aren't that clear.)

Was there an effort by Ezra Klein to exclude blacks from his vast left-wing conspiracy to shape the news, or was he blind to his own racism?

And yes, I'm calling JournoList a vast left-wing conspiracy. 400 people from journalism, academia, and public policy fields is "vast." Klein has acknowledged that he limited membership to "left or left-leaning." And as more and more leaks from their archives, the "conspiracy" is becoming more and more apparent. But I digress...

Now, will the Democratic party, MSNBC, and JournoList address their obvious racism and atone for their sins?

Yeah, I doubt it, too.
