Imagine that you're about to bite into a soft, creamy, delicious banana, when someone runs over yelling "STOP! THAT'S RADIOACTIVE!", and smacks it out of your hand. I imagine you'd be pretty upset at that point, probably wonder what this weirdo's going on about. Radioactive? WTF? It's a fruit, not a nuclear fuel rod!
But you see, on the most technical level...the guy's right. Bananas are radioactive. They contain Potassium-40 and other isotopes. His actions, however, remain ridiculous. Eating a banana is obviously not dangerous. It would require eating 100,000,000 bananas at once to deliver a fatal dose of radiation, and the attempt would kill you for a host of other reasons long before you got to even 1,000,000 bananas.
And while bananas are a well known example,
literally everything emits some minute, harmless trace amount of background radiation.
Even our own bodies.
But what would you say to someone who told you "everything is radioactive!", and began to point at random objects around you going "that's radioactive! And that's radioactive! And so's that!"? Not someone who seemed to just be sharing an interesting though largely useless scientific factoid, but someone who seemed to be expecting you to DO something, to respond as though you'd just been informed that....well that you were around something radioactive?
You'd think that person was pretty nuts, right? Because as much as the statement "everything is radioactive" is true in the most technical sense, employing the broadest conceivable definition of radioactivity, it's also useless and absurd, and embracing it would make calling something radioactive meaningless...and also ineffectual as a warning when one is about to encounter something that actually DOES emit a hazardous amount of radiation.
So that's not how in common parlance we use the term "radioactive". When 99.9999% of people call something radioactive, they mean that it is MEANINGFULLY so, that it emits enough radiation to warrant special caution.
Everything I just said about radiation applies to politics as well.
There's a common argument going around that "everything is political". Sometimes it's phrased "all media is political" or similar. By everything, people don't generally mean that rocks and air are political, of course, but they do mean everything human beings do and think and perceive.
And like with radiation, in the broadest possible sense they can defend this statement semantically. You can read between the lines of anything anyone does and certainly anything anyone creates, and glean some insight into how they see the world, their little unquestioned assumptions and biases, and you can play six degrees of Kevin Bacon between those details about a person and an outlook on politics. Theoretically, under this reasoning, the statement "the sky is blue" is political, since by framing the assertion in such factual terms, you're claiming an objective, observable reality, and thus discounting certain postmodernist beliefs.
But saying that belief in a blue sky is political is about as ridiculous as declaring bananas radioactive. You would have to make so many assumptions layered on top of other assumptions to get from belief in a blue sky to any viewpoint on nations, governance, or any hot-button modern issues that you would never be able to reliably guess a person's stances based on whether they said the sky is blue...and a different person could come to the opposite conclusion about what that person believes on basically any issue through another chain of assumptions that's no more or less valid and no more or less likely to be right. And as it applies to gaming, the basic "rescue the princess" excuse plot is no more likely to signal support for traditional gender roles than it is support for feudal monarchy. Really, such broad cliches are more like political inkblot tests. What you see in them says far more about what YOU believe than what the writer believes.
We've all been to a family or social gathering where someone has said "let's all get along and not bring up politics". And virtually nobody is actually CONFUSED as to what that statement means, just like virtually nobody is actually confused when someone says to avoid exposure to radiation.
But when someone says "I don't want politics in my video games" or "Super Mario isn't political", there sure are a lot of people who FEIGN confusion, who condescendingly explain to you that everything is political because everything a person does reveals some little tidbit about their belief system. And based on that definition they offer, they want ACTION, they want the politics they see in media to be called out, they want creators to be held accountable for their messaging. They are no more offering an abstract factoid than the person frantically pointing at a tree and screaming "IT'S RADIOACTIVE!!" Of course, I bet you could look through the histories of almost every person who's said that, and find some point where they've demonstrated understanding of the normal definition of politics, be it referring to a "political account" on twitter (after all, under their stated beliefs aren't all twitter accounts political accounts?), saying they "got political" about something (weren't they always political about everything?), or simply knew how to follow a "no politics" rule in a discussion space without assuming they'd be banned for any discussion of anything. So either they're disingenuous or their own actions prove them wrong and demonstrate that you CAN'T interpret a person's politics from throwaway statements and implicit assumptions like that. Well, either or both...most often, probably, both.
At the end of the day "everything is political" is a motte and bailey argument.
The motte is that it's possible to interpret small details about a person's worldview, their attitudes towards society, humanity, and life, from the things they do, say, and create...even if they're not consciously trying to make a point.
The bailey is that these guesses can be relied upon to judge a work or a creator, to draw conclusions about where they stand on tangentially related real world issues, or even to predict how other onlookers will interpret the same media, and that media creators have a social responsibility to include explicit political messaging that the arguer agrees with.
There may be trace amounts of politics in everything people do, just as there are trace amounts of radiation emitted by everything. But neither are meaningful or have any likely effect on people. Things can still be sorted into "political" and "not political" as easily as they can "radioactive" and "not radioactive" based on that standard. People understand a difference between the amount of politics in Metal Gear Solid and the amount of politics in Tetris just as easily as they do between the amount of radiation in uranium and the amount of radiation in breakfast cereal. One is meaningful and should be treated accordingly, the other is so negligible that it can reasonably be treated as not existing.
Dialectical analysis of Megaman is no more reasonable than that guy swatting a banana out of your hand. It's an ideological bludgeon, a tool for guilt tripping media creators by convincing them that they can't escape politics, or allow their audiences to do so, and thus must pick a side...the veiled threat that picking the wrong side will be met with severe social consequences is generally at least implied.
