It's important to distinguish between having opinions about policy and having opinions about politics. Having political opinions != identifying with a political party. I have lots of strong opinions about policy but few about politics.
Fyi, your post still came off as aloof, I think it's largely because of the word 'abstract'. I have a hard time understanding what it means to have an abstract opinion about either policy or politics, especially in a environment like LW where something like utilitarianism is more or less assumed. It seems to me that you either have strong opinions on politics or policy or you don't. Opinions don't seem to vary along an abstractness dimension in an interesting sense.
It is often the case that when more rational that average people say they are 'discussing politics' they actually mean they are discussing policy. You sound like you're trying to signal sophistication because you sound like you're pointing out that you've realized that it's policy not politics that's important, and among more-rational-than-average people this is a very obvious conclusion.
I don't distinguish between politics and policy.
I've long opposed discussing politics on Less Wrong. Elsewhere, however, I have been known to gaze into the abyss; and so it came to be that I wrote a handful of blog posts of the Oxford Libertarian Society Blog. I had the deliberate intention of bring a little bit of rationality into politics - and so of course ended up writing in something like Eliezer's style.
I wanted to establish some theory first, so the initial posts were about The Conservation of Expected Evidence and Reductionism, and then one particular Death-Spiral.
As you'll probably notice, one of my defences against the little-death has been to err on the side of attacking Libertarian positions; I provided an account of Traditional Socialist Values so we remember that our enemies aren't inherently evil, and then analysed an abuse of The Law of Comparative Advantage, showing cases where it didn't apply.
I can't promise I'll update at all regularly.
