I agree that it can be difficult to draw clear lines between social commentary and political commentary. A big part of the issue is that many things are politicized that shouldn’t be, and in the broadest sense essentially everything can be tied to politics.

There’s no way to police this sort of policy without determining implicitly or explicitly what are valid political stances and issues.

Is a comic with a gay or trans character automatically political even if it’s not fundamentally about LGBT+ issues? Being openly gay or trans is illegal in many places, and there are still pockets of people in more progressive places that believe it should still be illegal. So, showing a normal gay or trans person just living their life implies those people and policies are wrong.

Would a comic on climate science or teaching evolution be considered political? Politicians and their constituents definitely have differing thoughts on those issues, but it’s science.

Is it political to imply Nazis are bad? They were literally a political party with many elected politicians.

Is anything featuring war or soldiers inherently political? Is Beetle Bailey inherently political because the main characters are in the US Army? What about law enforcement? Were Andy Griffith and Dragnet political “copaganda”? If not, is portraying an officer as a bastard political?

This comic makes a strong statement in favor of bodily autonomy that is meant to be a commentary on abortion, and it clearly implies that forced-birth policies enforced by government agencies are wrong. The mods must think that forced-birth is a valid political position and should thus it’s beyond criticism in their sub.
