You apparently have never read or listened to more than the "I have a dream" speech. King was very much about anti-racism, which is best termed "anti-racism". It's not sufficient to not add racism to the world, you should seek to counter it. And no, that's not the same thing as being racist in another direction. If you can't tell the difference, maybe you should go study what MLK actually said.
On the other hand, King's notorious speech sounds absolutely nothing like Kendi or other current anti-racists, so evidently there's quite a gap between the two stances, and it's dishonest to deny it.
That speech is just one of many. But anyway, MLK was at the forefront of anti-racism 60 years ago; it would be more alarming if there weren't a gap between him and the current vanguard.
Curious why you described the speech as “notorious” rather than “famous”?
