Those are both things I see strong libertarian support for and little support outside the libertarian sphere.
People have this remarkable tendency to believe that they personally have thought through all their political beliefs, but everybody else is just going along with their political identity. I've seen a handful of people for whom this is the case; the vast majority choose their political identity based on their political beliefs.
Personally I think those who think politics are a mindkiller are just guilty of a jilted hubris; it's easier to claim other people can't change their minds than to accept that your arguments aren't as universally compelling as you thought.
ETA: My point in this comment wasn't the mindkiller parts, it was to point out that what somebody is inclined to believe is a "rational" political belief probably isn't nearly so obviously rational as they would like to think - the opposition probably isn't just mindkilled into opposing it, that is. Your "rational" political beliefs probably have decent evidence and arguments, which is why you hold them; don't assume they're slam-dunks without any decent counterarguments.

I don't think that's true at all; I would say that most liberals right now, and much of the country in general, are in favor of at least some movement on both of those issues. Legalization of marijuana, for example, now has majority support according to recent polls.
I was thinking about the hazards of bad government, and wondering if there was a way for the LW community to do something to oppose them, and it occurred to me that we might be picking up the problem by the wrong end.
The usual way of thinking about political action is to start with one's political identity (progressive, libertarian, whatever), and that's likely to put one at odds with people who have opposed identities.
Instead, I believe there are projects which could appeal to rationalists across a wide range of the political spectrum. A couple I can think of are opposing the war on drugs and improving judicial systems. Any other suggestions?
