I exist in several categories of people who’s right to exist have been threatened many, many times throughout history, I agree that everything is political, or rather, that politics encompasses everything.
However, not every discussion should become politically oriented, as it’s not particularly the most productive in many cases. This is most prominent on the internet, where nuance, which is ESSENTIAL for productive political discourse, is often absent. I find much political discussion. This is especially true in dialogues where it is either discussed on a broad scale, or where it is discussed in a reactionary manner. When my answers to political topics are so often “it depends”, this stuff tends to be quite straining, especially when my attempts to create dialogue are shot down.
In short “not everything is political” exists because you’re either detailing a discussion to talk about how horrible everything is, or you’re on the internet and internet politics just suck.
