The problem is that "partisan" doesn't automatically mean "wrong".
People wield "the middle" as if it is some magic incantation that makes them correct or immune to criticism. In fact, it is generally the "middle" or, as I prefer to call them, the "inert" that tend to be wrong since they are always behind the curve rather than ahead of it.
In Milgram's experiment, only the most "partisan" refused to deliver the shocks. The "middle" dutifully continued right to the end and delivered the highest voltages even as their own distress mounted.
You may avoid politics, but politics may not avoid you.
There isn't exactly a "curve" to be behind, just as there isn't one single "history" that you can end up "on the wrong side of". Politics is just the constantly shifting borders in a formalised war for power between different groups, long term there is no single direction of "progress".
>You may avoid politics, but politics may not avoid you.
This is the correct view, in the sense that if you don't belong to some kind of tribe, you'll get ripped off by someone who does. The inert group are not wrong, but by participating less than the others in the battle for their collective self interest, they will end up being the ones taken advantage of.
I am ok with being called inert. In the context, this would suggest I am less easily swayed than most.
