When a story does have political overlap, it's incumbent on commenters to stay within the site guidelines regardless of how strongly they feel, or how wrong they feel other people are. This is in the site guidelines: "Comments should get more thoughtful and substantive, not less, as a topic gets more divisive." That's not easy, but it's possible. For this forum to succeed at its mandate, we all have to work hard at it.
What people call "acknowledging blatant truths" can mean a lot of different things depending on their passions about a topic. It's hard to perceive one's own expressions objectively. Even the users who post the worst flamebait typically feel like they're simply stating the truth in a straightforward way.
There are ways of acknowledging truths that are more likely to lead to flamewar, and other ways that are less likely to lead to flamewar. We need commenters here to do the latter, not the former. That's an ongoing process that takes a conscious effort, at least when one's emotions are engaged, and people need to do this regardless of how right they are or feel they are.
