I've upvoted the thread because, while I disagree with its point, I think it's a good idea to infrequently re-analyze whether a subject is fit for discussion here. However, I might not upvote if I saw this (why not politics?) particular type of post appear very often.
I don't want to see macropolitical (using this as a made-up word to indicate non-micropolitical issues, as defined in prior comments) discussion on LW because they give me a lot less useful information than does almost any other type of discussion. I am personally very uninterested in politics given that my impact is likely to be extremely low in it, so I see it as a waste of computing power, a source of accidental mind-killing, and a source of negative emotion which may interfere with my ability to do more worthwhile things.
On the other hand, I would welcome posts on micropolitics -- I plan to take a 'donor' path and foresee that I will need to learn how to usefully interact and manipulate (without connotation) people in a corporate setting and such.
There is a tendency to downvote articles and commentaries with a political subtext with a remark on how politics is the mind-killer. I completely understand that nobody wants his mind to be killed, however, I disagree on the employed methods. I don't think anybody can really afford to ignore politics. It's a fact about any group of even a handful of people. Thus instead of shunning politics I think it's better to build one's rational defenses. Understanding that politics is a problem is only the first step. If you stop there, there will always be a big part of life where you are not rational. Therefore I suggest that, as long as it doesn't get out of hands, there should always be room for political discussions if not on the main site at least in the discussion section.
