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".
Yeah generally when talking about a thing you draw a circle around the thing, that's how that works. My glass from ikea isn't making any political statement or assumption in its design as a finished product (unless you consider presumed size requirement for a beverage container to be political, though inherently nothing about it even states its purpose, so even that is doubtful) the process behind its design, manufacturing, and sale very much is political as fuck though.
