My point here is that atmosphere of hobby spaces is politically charged right now because Trump is the kind of President who has to be upending things, has to be at the center of the national conversation at all times, and because the right generally has made it their mission to attack the culture that doesn't conform to what they want constantly. 

Sure, in this one instance, some mods could have made an executive decision. But the reason politics is pervasive in Reddit hobby spaces goes way beyond that, and it's because the right is aggressively politicizing (and attempting to influence) every aspect of American life.
