I could interpret that statement to mean that libertarianism, which holds few political beliefs at all, is correct.
Where do you get the idea that libertarianism don't have many political beliefs?
A liberatrian can usually tell you that a particular government program is bad without looking at the merits of the particular program.
Take minimum wage. I personally don't know whether it's a good policy. There are theoretical market based arguments that it's a bad policy. On the other hand the published empirical evidence suggest that it's no bad policy. But then the data we have isn't that good. We don't have randomized control trials of mininum wage laws.
I don't have a solid belief on the minimum wage. I have thought about the issue and I believe that the evidence to decide just isn't there.
Do you think beliefs about the efficacy of minimum wage are necessary to promote or reject it?
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?
