See, but,
@Mercurius why do we need a "big tent" at all if there's no connection? After all, if there's no connection to any real world peoples, no parallels, then, well, there's no problem. That's the argument that gets recycled over and over again.
To me, it's mind blowing that you could look at that and not see the parallels.
Just as a point though, your #2 has never been an issue. There's absolutely no problem with depicting a fantasy race in a negative light. No one has ever argued otherwise. And, frankly, it's that number 2 that seems to be causing the problems. "Well, if we can't show orcs in a negative light, that must mean we can't show anything in a negative light" goes the argument.
Which has never actually been the problem. You can most certainly show orcs in a negative light. That's not a problem. Just not THAT particular negative light which is far too close to the negative light used to depict real world minorities. Doesn't matter which minorities, that's another red herring that's been brought forward as a counter argument. The simple fact that this language mirrors real world language makes it problematic.
No one gives a damn that vampires, dragons and beholders are described as evil because the way those monsters are described do not mirror the very real world language that is being used for orcs. Describe this or that race as evil all you like. Not a problem. Just leave THAT PARTICULAR description on the editing room floor and pick another one.
But, yeah, the solutions have already been offered in the thread. A bit of editing, a bit of changing the wording here and there and we're good to go.
