I've seen this a number of times, so thought I'd ask if there was a consensus on it.
I see your regular interpersonal questions, and in the comments somebody injects a heavily political comment. Imagine a "How do I not argue with my boyfriend" kind of question, and in one of the comments someone soothes "Don't worry honey, we're all human beings here (except [specific politician] supporters)".
This is annoying because it's out of place, and because one can't jump in and challenge the assertion without further derailing OP's actual problem. It's ... unseemly.
Doesn't even matter if [specific politician] or whatever is one that I like. It seems like an abuse to bring the politics in knowing that others will be reluctant to respond, and it's also kind of a heavy statement to leave unchallenged.
What does the community do in such situations?
