Lofgren writes in comments to yesterday's post:
I don't think McWhorter is proposing an alternative, "better" timeline. He's just making an observation about how the shift from Black-led street action to (often) White-led government action affect his own feelings as a Black man. Even in the quoted section, he explicitly says that he wouldn't want to live in the alternate timeline that you are proposing. It's not as though this observation is unique to him, though it is usually not framed around a personal feeling. Usually it is framed around historicity, specifically how ending segregation and the Civil Rights movement are often portrayed as great leaps forward for White people, who have learned an important lesson about sharing and caring and are graciously letting Black people act like they are equals (for now). A not so subtle implication, which MAGAs pick up on even if Liberals don't, is that all of this equality is kind of a trial offer from White America, which we can revoke whenever we want because it was not properly "earned" – i.e. taken from us – if it causes us too much trouble. This is not some crazy, out-there observation by McWhorter. He's not crazy to feel this way. It's the way the story is taught and the way that a majority of White America still views it.
I think you are being more than a bit unfair in your tweets and you seem to have missed important nuance. Like most eggheads, McWhorter wallows in nuance and likes to introduce extra nuance whenever possible, even when it is probably counterproductive or even illusory. You're criticizing him for failing at sci-fi style world building but he's just trying to express his feelings, not propose a spec script for HBO. It's not even like he is pretending to be rational. He's explicitly talking about emotions, not logic or reality. I don't think it's right to invalidate those emotions out of hand because they might lead to less optimal outcomes if he ever gets his hand on a time machine.
I have no idea where this reading is coming from. I was not criticizing McWhorter for "failing at sci-fi style world building". As Lofgren notes, McWhorter himself says that "none of us would want to rewind the tape and play things out again without the Civil Rights Act..." I was certainly not proposing an alternate timeline either. Did he read the tweets?
