I watched the youtube clip where Scott Adams did his racist star turn, and another where he "explained" himself.

It seemed clear that he knew he would lose the strip. He was quite deliberate about it.

More like a career move than an outburst. Planned cancelling.

Not the quiet part said out loud, but the loud part delivered quietly and calmly.

@jayrosen_nyu Adams has been wading deep in the alt-right cesspool even before that was even a thing, yet he was never a figure head of the whole movement. I think his controversies predate 4chan, if you can believe it. Nor was he ever one of its relevant mouthpieces or its spin doctors. When he was big he was mostly know for his misogyny but guess what, there is racism in there too. Morally ambiguous from the start he just turned to full moral bankruptcy to stave of irrelevance a little longer.
Scott Adams

Scott Adams (1957–) has a self-reported IQ of 185, and don't you forget it.[4] He is an American trained hypnotist[5] and cartoonist known for Dilbert, a long-running satirical comic strip about a white-collar office worker in America. His blog, which is currently a fascinating study of a man going insane,[6] attracted major media attention during the 2016 election. Long before that, he advanced some crank positions, including questioning evolution and the validity of the fossil record. He has appeared on InfoWars, further cementing his genius IQ.[7]

@MattFerrel @cli @jayrosen_nyu I'm not sure how I avoided all this. It seems like early in his career he hadn't gone off the edge yet, he still had some humility. I'm not sure when he went off the rails and started believing in his own infallible brilliance. I'm guessing some time after he released God's Debris, maybe even before.
