Here's my shot at what it would look like:
"Hey guys, I understand contemporary politics is not considered appropriate for this site, so I've started writing a series of posts on my own blog; here's the link if anyone wants to check it out."
It so happens that, as a libertarian, I sympathize with your agenda (and would happily follow the link if you did the above) but at the same time I don't think you can write a political post while leaving out the politics. (Eliezer managed to write some good posts about politics while leaving out the politics, which was a non-trivial feat in itself; I think that's about the best you can do.) And there are good reasons why we try to avoid politics on Less Wrong. So the best I can suggest is to write what you want to write on a blog where it's appropriate.
I agree with this.
I have libertarian intuitions (I take Keep Your Identity Small to heart). I have spent quite a while thinking about policy and economics and I think I can discuss it fairly rationally.
Even if you can discuss policy rationally, lots of people have not invested the time into developing that skill. Moreover, it's a much less useful skill than it seems like; coming up with correct answers in policy isn't very useful because it's very difficult to implement the implications of those correct answers (see here and here).
Politics is the mind-killer; but rationality is the science of /winning/, even when dealing with political issues.
I've been trying to apply LessWrong and Bayesian methods to the premises and favored issues of a particular political group. (Their most basic premise is roughly equivalent to declaring that Iterated Prisoner's Dilemma programs should be 'nice'.) But, given how quickly my previous thread trying to explore this issue was downvoted into disappearing, and many of the comments I've received on similar threads, I may have a rather large blind spot preventing me from being able /to/ properly apply LW methods in this area.
So I'll try a different approach - instead of giving it a go myself again, I'll simply ask, what do /you/ think a good LW post about liberty, freedom, and fundamental human rights would look like?
