Seriously. Every form of entertainment has baked-in political assumptions, and that definitely includes #ttrpg . You might choose not to examine them, but this is an active choice on your part, and you don't get to pretend that your entertainment is "free of politics".
I'm not sure about always. That's just lazy world building to have orcs naturally evil instead of predominantly mind controlled or ruled by evil leaders or some sort of blood fued. It's the same with good aligned races. Unless you want to focus on the definition of good and evil.
