Okay, short version. Eberron is not D&D. Orcs are listed as CE in the MM. Therefore unless you change it for your campaign the majority of, if not all, orcs are CE.We could certainly talk about problematic elements in the historical tradition and depiction of these various monsters, but (1) that doesn't erase the problematic elements of orcs in D&D, and (2) I don't see what trying to deflect the conversation to other monsters is meant to accomplish.
This is a truism that doesn't actually refute anything.
Sorry, Oofta, but I'm not sure why you think that explaining your reasoning somehow makes your strawman less of a strawman. A strawman isn't dependent on how much text you write or whether you explained yourself, but, rather, on how faithfully you present the argument of the opposition, and this is certainly not a position that I have espoused, nor can I recall @Hussar arguing as much either, so it does come across as a strawman. So your outrage about how this position represents the poor treatment of Native Americans comes across as feigned for the purpose of deflecting from how depicting orcs as immutable chaotic evil subhumans is problematically rooted in historically racist tropes.
Would you like to know why orcs are far less problematic in Eberron when CE orcs also exist in their setting? Because there are multiple cultures of orcs with a variety of indigenous religious practices and beliefs and not inherently predisposed to evil. There is not just a singular orc indigenous culture that is contrasted to a "civilized" culture. There are multiple orc cultures in the Shadow Marches and the Eldeen Reaches. The orcs that reside in the Mror Holds have a different culture than those that reside in Droaam who have a different culture than the orcs that reside in the Demon Wastes.
I think saying that the majority of orcs or any intelligent creatures in the MM are evil because of culture and religion is pretty awful. I think it's better to just state that they are not human and are simply wired to be evil just like demons.
I don't see how any of that can be considered a strawman except as just a way of saying "I'm right you're wrong".
Whether Eberron has a better take on this or not is not relevant to D&D as a whole.
