I did not mention a plot because I see no plot. I take a black-box, materialist view of history — what comes out is what the people in the box want to come out.
I sometimes refer to Second Wave feminism as the Great White Hope. White men didn’t plot to give the best jobs in the expanding economy to their wives and daughters, but they let it happen while black unemployment remained intractable. Post hoc ergo propter hoc. Sometimes that’s true, sometimes it isn’t.
For some people, having something to rebel against is a good enough outcome. Jill Stein supporters put Donald Trump in the White House. They didn’t want to, but they didn’t want not to badly enough to vote for Hillary. You can’t swing a dead cat without hitting a leftist who will tell you there’s not a dimes’ worth of difference between the Democrats and Republicans. They aren’t plotting; they just don’t give a damn.
Also, “the “demands of a black-led movement” were not the subject of my comment. Some of those demands make sense to me, and some seem short-sighted. But that’s as may be. My comment was about the slogan “Defund police,” which I see as a great big “Push me” button for someone who might want to change the subject. It was a dumb choice, forcing Democrats to disavow it and impairing their chances of unseating Trump, winning back the Senate, etc. It’s not clear to me how you transmogrified my critique of a slogan into a comment on the underlying demands that the article is at pains to distinguish, but I thought I should clear that up.
