Nope. But, we do need the option. Juliet of Romeo and Juliet was played by a boy for a long, long time. Does that mean that every single stage and movie production of Shakespeare's Romeo and Juliet must feature a boy playing Juliet?
We're obsessing with Tolkien because invoking Tolkien is pretty much the same as Godwinning a thread. It must be obsessed over.

But, if you'd like, we can point to a swath of works all the way up to current day showing the direct connection between "brutish humanoid" and depictions of various minorities.
The fact that suggesting that PoC play elves in the new Amazon version of LotR creates a storm of folks coming out of the woodwork to decry it, shows that this isn't just some academic issue that only a few people know about.
It shouldn't matter one whit that PoC play elves in Tolkien. If they want to have Idris Alba play Elrond, it shouldn't matter at all.
But it does. And that's the problem.
So, when a player declares that he's slaughtering the non-combatants, orc babies for example, you have zero problem? It's perfectly acceptable to commit genocide on these creatures? After all, they have no free will. They aren't capable of anything but evil, so, killing them is perfectly fine, regardless of circumstance.
I don't know about you, but, that notion makes my skin crawl. Why not just use demons? After all, that's what you've done - made demons (unredeemable evil) and put them in meat suits that are linked to racist depictions of minorities.
You really have no idea why someone seeing that might have an issue?
