That talking point has been beaten to death by people you can't actually debate his points on Obama.
We have to stop that talking point with no proof.
He said it on air multiple times.
Here is a full print interview and the excerpt of his comments below
NPR Choice page
From Aug 2010
COX: Have you communicated with him personally?
Prof. WEST: Well, I'll tell you, I had not talked to my dear brother since the Martin Luther King gathering in South Carolina, and very briefly Super Tuesday. But he did come and make a beeline to me after his speech on I think it was Thursday morning in Washington, D.C. I hadn't seen him for two and a half weeks, and he made a beeline to me, though, brother, and he was deeply upset. He talked to me like I was a Cub Scout, and he was a pack master, you know what I mean?
I said, well, my mother and father raised me right. I respect my dear brother, but I don't like to be demeaned and humiliated in that way, and I didn't get a chance to respond to him. And I hope maybe at some time we can. But it was very, it was a very ugly kind of moment, it seems to me, and that disturbs me because then it raises the question for me: Does he have a double standard for black critics as opposed to white critics?
Frank Rich, Paul Krugman, Maureen Dowd, a whole host of brilliant, courageous critics say all kinds of things, and he treats them with respect. They get invited to the White House. I say the same thing, he talks to me like I'm a Cub Scout.
I dont like that. It raises the question, too, is, you know, how many black folk need to be sacrificed for his campaign and his governance...
==============
President Obama welcomed and gave access to several Black intellectuals and leaders, so Dr. West was forced to drop the "he sacrifices/drops Blacks who criticize him" angle.
Remember Obama was inaugurated in Jan 2009, this article is from a year and a half later.
I love and respect Dr. West, but he openly mentioned the snub multiple times, and that was the main reason he went in on Obama.
