None of the major political ideologies are particularly consequentialist in the way they approach policy.

I like your whole comment, but disagree with the first sentence.

Apart from reading about it explicitly on LW, I was also able to approach politics as less of a mind-killer once I realized that different ideologies approach issues believing different outcomes would be ideal. But neither side realizes that (or how very different "ideal" is to each), so one just says, "ABC will work! XYZ is crazy!!" and the other says, "What?! ABC will never work! History shows XYZ is clearly the best policy!" Each side means something different by "work", and so spiralling mind-kill ensues...

Actually, I've found my best friends, with whom I end up discussing politics with, are very consequentalist, and care very much about what ends up "working best". Those who disagree with me simply don't define "working" or "best" in the same way I do, and so we really ending up talking past each other and giving each other funny, mind-killed looks.

For instance, as a liberal, I concede de-regulation is better for maximizing economic growth and so I concede that right-wing fiscal policy is "better" to that end. But I'm admittedly more interested in anti-oppressionizing the world (a la your strawman progressive) and providing the basis for relatively economic equality than I am in max growth, so I am for more regulation and wealth redistribution to that end. We each believe the best possible world looks differently, and so we are asking different questions when we ask the same question. But we are approaching the issue from a consequentialist standpoint.

And so my righty friends still think I'm a bleeding-heart weirdo and I think they are greedy and heartless ;) ...but at least we've moved our discussion passed arguing over definitions without realizing that's what we were doing.
