I'll phrase it like a shower thought:
"Avoiding politics is about as useless as avoiding economics, math, science, or the arts; they permeate everything we do. We even use them to define what it means to be human. We might as well avoid breathing."
I think avoiding partisanship and incivility might be more productive, but it has the problem of being more vague and requiring judgement, thus requiring more effort to enforce fairly and consistently. I don't think there is an answer that will satisfy everyone. Avoiding politics may be a good rule for this community, even if it's pointless.
You're a biological garbage disposal and your shit goes down the same sanitary sewer line. It's just food scraps like peels, stems, and trimmings. Hardly qualifies as 'insane'.
