There's a lot of people still operating under the assumption that the older meanings of the terms are in use, because most people have better things to do than to stay up-to-date on this sort of stuff when they've got lives to lead and their own problems, not to mention the fact that there's some deliberate obfuscation that tends to go on.
The MLK quote is such a red herring. It's a nice statement, but what one guy said 50 years ago doesn't define a culture or society.
You misunderstand my point entirely. I am not "advocating" for that position today. Nor am I not advocating for it. I am staying neutral on the "ought" in this series of posts.
I am saying that when I was 10, that was the "left-wing" position. Many people still think it is, because they don't keep up with all this stuff. As you are rather handily demonstrating, it is not today. (I was a bit concerned when I mentioned it that people would just be contrary and deny the patently obvious fact that it is no longer an acceptable left-wing position, but now I don't have to worry about that.)
I will also say that the prickliness you've been programmed to fire back with, as evidenced by the rest of your thread, is a non-trivial part of the problem. You've been left unable to understand what anyone is actually saying, instead of what you think they are saying, as evidenced by your reaction to what I wrote. You may prove me wrong by replying to this without bulldoggedly arguing about whether implicit bias exists. Should you succeed I promise to acknowledge that.
In fact, the 70's and 80's were all about embracing blackness.
If i were prickly, i'd be making insinuations about you personally.
I think what we're looking for is that it's just another attribute, no different from whether the person has blue or green or brown eyes, or what style shoes they're wearing.
In a conversation with my boss the other day, a newly-hired AWS engineer came up. I've met him just once, and helped him get situated because his desk is near my team. I realized that although I'd interacted with him to that degree, I had absolutely no recollection of what his race was (describing him was a logical part of that conversation). I think this is what's sought.
The ideal answer is not to completely drop any diversity effort, but on one side (the "revolutionaries") to recognise where they turn into zealotry, and on the other ("the entrenched", of any type) to accept they might have to lose something to gain something.
