Sure, as long as it's there as a character or national flaw. Orcs are not a systemically oppressed people, as they do not exist, and real orcs will not be hurt by in-game oppression.
Okay, so how do you know they didn't just write that in as a character flaw so they could be racist against players who are a race they actually, ya know, dislike or whatever. There is absolutely no way to prove their out-of-game viewpoints, so it's enabling them to be racist with no consequence of any discernible nature.
