Thanks for your reply. The first few paragraphs are educational and appreciated.
We may disagree on the last one - I find "everybody understands..." assumptions can range from mostly happen to be true to tragically incorrect to manipulatively deceptive. Based on other discussions in this thread, I'm not alone. The fact that you indicate diversity and inclusion has moved away from equal treatment phrase, that Equal vs Fair is now being taught as basic differentiation just like Pretend vs Real, and Opinion vs Fact in school, also I believe supports my claim these are meaningfully, substantially, importantly different concepts. Again, I think they get confused enough, intentionally or unintentionally, that "everybody understands" is just too dangerous of an approach, even if well meant.
What it empathically is not, by definition, is "equal treatment". It's existence is epitome of unequal treatment.
