Well probably, immigration and gender are both things that people have basically always had strong feelings about. Though I see your point; what if it’s more of a top-down phenomenon and wouldn’t be a big deal without the propaganda? But in that case the apparent anti-democratic message of the comic seems similar; the task of good politicians being to manipulate people in more responsible directions they actually believe in and not just lazily seek power appealing to whatever stupid ideas, which still seems to imply voters are not and should not actually be making any real decisions or in charge of anything.

Maybe it could also be thought of the other way around though; if ‘bones’ represents something actually pretty bad, then despite being ruled by a group naturally interested in doing the wrong thing, the right thing gets done anyway because of their incentives and lazy greed.
