There is literally no right answer, the very nature of modern diversity is that it will always be a moving target. That is until we get over the entire concept of diversity which is racist / discriminatory at it's core.
That's incorrect. The main use of diversity is in an antiracist fashion. I'd suggest you read one of Kendi's books. Stamped from the Beginning has clear and readable descriptions of the difference, but it's a relatively long work, so you might start with one of his shorter books.
Instead of dismissing the argument with a tawdry negated statement and a book suggestion, do you have some thoughts of your own with this matter, or at least some kind of summary?
Long ago I learned that it was rarely worth my time to try to argue online people out of their ignorance. A rando with a throwaway account, a strident tone, and a fair bit of ignorance on the topic is almost a guarantee that that's no point.
If you're interested in knowing something about the topic, you'll do some work. If you aren't, no amount of me spoon-feeding you summaries of serious scholarly works will change that.
If you do end up learning something and have questions, feel free to email me. I'm glad to discuss the topics with people who are serious about it.
What distinction does a throwaway account make on an otherwise-anonymous online forum? No need to take discussion offline. Within the next decade, I am in confident the pendulum will swing the other way, and the people who are able to vocalize their opinions now in public will be the ones needing throwaway accounts.
That's another very ignorant question. You can look up the literature on it. (Heck, you could have just followed a link in my bio to get a start.) But again, I'm not spoon-feeding you.
