I live in Australia, not the USA. Party politics seem to be less divisive here than in the USA.
I notice that there seems to be a tendency for questions related even tenuously to politics or economics to earn comments that, from my perspective, serve as little more than tribal markings to indicate the US political party the commenter belongs to, without contributing significantly to the discussion.
To my ears, it is like every question related to soccer/football earned a few comments saying "This sounds like the typical lies Manchester United supporters would share. Go Arsenal!" even if the question was about the meaning of the offside rule.
Each individual comment is innocuous enough, but the repetitive nature of them seems divisive to me.
Is this just a cultural difference I should learn to tolerate? Is this a part of our tribal psyche that will never go away? Should we be less tolerant of them? If so where is the line, and what action would be most appropriate, without impacting our ability to question and get to the truth?
