Yes, any solution will always be asymptotic. Doesn't mean that you shouldn't try your best. Exclusion will never disappear completely, but that is in no way a reason not to try and reduce it wherever and however we can.
And then it purely becomes a question of "can we justify this?". There will never be universal agreement on this - it's just about presenting a case, and seeing how convincing it ends up being. I don't think there's a good CREATIVE reason to exclude black actors from playing Galadriel. But there may be good ECONOMIC reasons, which you can judge morally however you wish. Studios aren't people. They'll want to make money, and if that means screwing over minorities in the process, so be it. Until that costs them more money than not doing it, there's little reason for them to change. Be that as morally repugnant as it may.
And let's be clear here: you are still misunderstanding the word 'exclusion'. It doesn't mean "let's go round up all the black people, see if they want the job". It means removing barriers for them to make the choice to apply THEMSELVES. Some of those barriers are explicit, some are implicit. But my point is solely about reducing exclusion, not about actively filling quotas.
That's our judgement to make, collectively. What is or is not a good reason needs to be negotiated. That's how all discourse works.
No, but that works both ways. You can't implicitly accept one default without justification, like "it was traditionally done that way" - that's a logical fallacy (argument from tradition), not an actual justification. ESPECIALLY when the issue is that we would perhaps like to CHANGE how we've always done things, because how we've always done things was, in a lot of ways, racist and bigoted. That's the problem, so you can't simply skirt the issue by appealing to a tradition that is in fact very much at stake in the first place.
Those are very much not the same thing. They're interrelated, but they are not synonymous. Grossly negligent to use them interchangeably, implicitly or explicitly.
"Absence of diversity" is a much more complicated problem, and it's very difficult to assess broadly. My focus is purely on exclusion in this debate, because that's a concrete angle of attack. There's a separate discussion about the absence (or presence) of diversity that can and should be had, but it's far more difficult to engage with.
Cool. Something I never questioned or disagreed with or even... talked about. I only ever talked about exclusion. That you have trouble with distinguishing that from diversity and its absence/presence isn't on me. Don't try and bring this in as though this was a point of contention - I never engaged with it that way, at all.
It does if you make simple equivocation fallacies (see above), because it betrays ignorance about core issues. Trying to paint over things as though they were the same when they're not is exactly what's problematic about it.
I don't, and never have. That being said, absence can be INDICATIVE of exclusion, and not all exclusion is explicit. You can claim all you want "but we never stopped people from applying!" when the framework of the entire process makes it clear that would be futile - those are implicit barriers, and they're very tricky to deal with. One good example for this is women in STEM fields - no one actually actively stops them from going into STEM, but there is a slew of implicit barriers that makes them not want to go into STEM. And that IS a form of exclusion, just not a very visible, very explicit form.
But still: that does NOT make absence of diversity and exclusion the same thing. It only makes them related in certain ways.
That's relevant to Hollywood, too. It takes a lot for an actor of color to go to a casting for a role that's always been or is strongly described as white - even if no one stops them from trying out for the role, a lot of people simply won't bother because they are convinced they'll never get it. That's an implicit barrier, and implicit exclusion, and it's very difficult to tackle.
