As left-wing rants go, Cornel West has just given us one of the best to come down the pike in quite some time.

Like most left-wing rants, West's is overflowing with self-righteousness, brimming with high dudgeon and reeking of hypocrisy.

West is a college professor and a member of the Democratic Socialists of America. He's so far to the left that he makes President Obama look like a moderate.

And it's Obama that was the target of West's rant, which he delivered on a radio show called "Democracy Now."

West gave his take on Obama's recent remarks about the acquittal in the George Zimmerman trial, and he wasn't kind to the president.

"President Obama is a global George Zimmerman," West huffed, "because he tries to rationalize the killing of innocent children, 221 so far, in the name of self-defense, so that there's actually parallels here.

"In Pakistan, Somalia, Yemen. So when he comes to talk about the killing of an innocent person, you say, 'Well, wait a minute. What kind of moral authority are you bringing?' "

The appalling hypocrisy in West's rant can be found if you read the full transcript of his "Democracy Now" interview. West, commenting on Obama's statement that he could have been Trayvon Martin 35 years ago, had this to say:

"Will that identification hide and conceal the fact there's a criminal justice system in place that has nearly destroyed two generations of precious, poor black and brown brothers?"

Precious? Among those "poor, precious black brothers" is one Darrell Brooks. On Oct. 16, 2002, Brooks kicked in the door of the Dawson family in East Baltimore.

Brooks tossed gasoline into the house and set it ablaze. All seven occupants of the house died. They included Carnell Dawson, Angela Dawson and their five children: Lawanda, Juan, Carnell Jr., Kevin and Keith.

I've given the names of the parents and the children because I'm convinced that, should West stumble on this column, that it will be the first time he's heard of the Dawsons.

All five of those children Brooks so callously murdered were every bit as innocent as the children in Pakistan, Somalia and Yemen for whom West sheds so many tears.

So, in Westworld, when Obama kills innocent children, it's a heinous act that eviscerates, if not eliminates, the president's moral authority.

But when West's "precious" Darrell Brooks murders five innocent children, well, that's just tough luck for those children. Kind of makes you question West's "moral authority," doesn't it?

There was more — much more — to West's rant. Being the typical, diehard, black leftist he is, West resorted to a bit of race-baiting in his comments, dredging up images of slavery and even invoking the "n" word.

"I think we have to recognize that he has been able to hide and conceal that criminalizing of the black poor as what I call the 're-n------zing' of the black professional class.

"You've got these black leaders on the Obama plantation, won't say a criminal word about the master in the big house, will only try to tame the field folk so that they're not critical of the master in the big house."

Such remarks stand for themselves, as does the one West made about the stand-your-ground laws in several states.

"Well, I certainly agree with [Obama] that we ought to fight 'stand your ground' laws, but we've got to keep in mind 'stand your ground' laws are part of the legacy of the slave patrol, which is to say it's primarily white brothers and sisters armed to keep black people under control."

How, to paraphrase a classic line from the superb novel "A Confederacy of Dunces," do we get through to a mind like West's?

We don't. We can't. Indeed, why would we want to? Isn't the conservatives' greatest weapon against the left in America letting left-wingers talk, rant and rave?
