Brussel sprouts used to be truly awful, made me literally wretch. Now I eagerly make and order them as a bar snack.
To be fair there are two reasons beyond my changing tastes for this. First, my mom liked to steam brussel sprouts whole and serve them with margarine, salt, and pepper, now I generally cold sear them or roast them in the oven with much better seasoning. Maybe even some bacon pieces and blue cheese mixed in. Second, brussel sprouts did actually change over time to get less bitter and awful since I was a kid.
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.
