But the video isn’t about white liberal commentators. The video is about everday white liberals. So now who is putting forth the strawman argument, John?

But, if you’re curious about more established white liberals who have expressed white guilt and/or contempt, then here is an example:

Tom Hayden is an American social and political activist, author, and politician, and director of the Peace and Justice Resource Center. During 1976, Hayden made a primary-election challenge to serving California U.S. Senator John V. Tunney. Starting far behind, Hayden mounted a spirited campaign and finished a surprisingly close second in the Democratic primary. He and Fonda later initiated the Campaign for Economic Democracy (CED), which formed a close alliance with then-Governor Jerry Brown and promoted solar energy, environmental protection, and renters’ rights policies as well as candidates for local office throughout California, some 100 of whom would be elected. Hayden later served in the California State Assembly (1982–1992) and the State Senate (1992–2000).

A few years ago Hayden’s son married Simone Bent who is of African descent. It has been reported in the May 9th issue of The New Yorker that Tom Hayden honoured his son’s marriage in the following manner:

As the evening progressed, the parents of both the bride and groom made speeches. Speaking off the cuff, Garity’s father, the political activist and politician Tom Hayden, who was Fonda’s second husband (neither parent want Troy to bear the weight of a famous last name), said that he was especially happy about his son’s union with Bent, who is black, because, among other things, it was “another step in a long-term goal of mine: the peaceful, nonviolent disappearance of the white race.”

[Perhaps not the commentary that you’re looking for, but it’s the example of an established white Liberal that I have off the top of my head.]
