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 mean I can understand having occasional exceptions to the rule so the players can get an interesting non standard experience, but straight evil aligned critters should always be present in fantasy settings especially ttrpg and DND specifically.
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.
