I came in to this question from the Hot Network Questions sidebar.
It does not reflect well on this Stack site to drop in on a question and see a moderator having a friendly comment exchange with another user and exchanging off-topic political takes. Comments are not for extended discussion; Stack Exchange sites are not discussion fora; the purpose of comments on a question should be to help refine and understand the question and not anything else; and moderators are supposed to know these things.
