You’ve misunderstood so many of my points, this is exhausting.
You insist on gatekeeping the term “raceswap”. Fine. Call it “reimagining an existing character as another race”, if you want. You would have to be delusional to deny that Miles Morales is a Black-Latino version of Spider-Man.
The article I linked to mentions the backlash and controversy about political correctness and Morales. I’m a little surprised you missed the point there.
I’m not sure what specifically you’re on about with the “usual crowd” paragraph. I know that lots of non-racists are also against “reimagining an existing character as another race”. I agree that race swaps can go wrong a lot.
Please read this carefully: The specific claim I am contesting is OP’s strong thesis that raceswapping is always bad. I gave examples of it sometimes being good. Miles Morales is certainly an example, down to the criticisms of too much political correctness, racists complaining, fan “controversy”, claims that it’s a cash grab, etc.
My point was not that the multiverse is bad like elf slavery is bad. I am saying that your explanation gets things backwards: the multiverse doesn’t show how it’s not a race swap. On the contrary, the race swap is the reason why they needed to use the multiverse as a narrative tool. Forget the analogy to elf slavery if you don’t get it. The point is that some writer wrote a multiverse storyline in order to justify the existence of a Spider-Man of a different race.
