Point me anywhere that the skin tone of Dwarves was meant to represent Jews in real life just the same.
Your argument is just as baseless and without merit. You're merely correlating the fact that the inspiration was Medieval Jews to any depiction you see fit, whereas the truth of the matter lies deeper than your personal interpretations.
I mean, you're literally trying to argue technicalities here. You might as well imply that Dwarves wear yamakas and spin dreidels during their festival of lights.
Tolkien's work was never meant to be a mirror of real life, so I'm not sure why you're holding the skin tone of Dwarves to a standard of reflecting that of the real life culture they are based on. We know skin color is not one of the things described in the novels. What we understand of what the skin tones could be is literally based on the fact it lacks a description, and contextualizing it in a narrative where physical details are usually denoted when they are considered worth noting, typically because of an exotic nature.
Like the whole depiction of long-eared Elves in fantasy derives from Tolkien's own fiction, yet is generally a creative liberty taken by fantasy artists who then run with the depiction, whereas the original source merely implies that Elven ears are merely slightly more pointed versions of Human ears. There is no specific depiction on how long an Elf's ears really are, whether they'd be crazy long like we see in Warcraft or in Anime fantasy depictions, or if they're just slightly pointed like we see in traditional Tolkien adaptations. There is no right or wrong answer there, and the commonly accepted Tolkien Elf is the one that doesn't take radical creative liberties with its interpretation. It doesn't mean Tolkien Elves can't be depicted with radically long ears, it just means it wouldn't be a commonly accepted interpretation of Tolkien's work.
Cuz let's be clear, while there is no right or wrong for depicting diverse skin tones for Dwarves, it will not be a commonly accepted interpretation of Tolkien's work. Just like no one commonly accepts long-eared Elves as being that of the Middle Earth variety, even though it very well could be. And for that matter, we could extend that to many other fantasy tropes that have derived from Tolkien's works as well that do not retroactively apply to Tolkien's own works, like bright green skinned Orcs and Goblins. There would be nothing wrong with having a Middle Earth adaptation with a bright green skinned goblin or orc, but it wouldn't be a commonly accepted interpretation of the original work.
