Actually, immigrants flee poor states to go to prosperous states. It does not follow, however, that immigrants understand why the new state is more prosperous than their old state–or that their cultural bias toward collectivism suddenly disappears when crossing the border into low-welfare state. Many liberal Democrats have fled California to escape high taxes. Does that mean they have abandoned liberalism? I doubt it.

Most libertarians do make anti-militarism a key issue: libertarians started and are the major contributors to antiwar.com, and the LP has a solid anti-intervention platform. I agree that anti-militarism MUST be a key issue (maybe even THE key issue) for anyone who is serious about liberty. Of course, those whose opposition to militarism mysteriously disappeared at noon on January 20, 2009 (or at noon on January 20, 2001) are beneath contempt.

And, of course, I share your view that freedom of movement must be brought to the forefront, which is why I wrote this post. I haven’t seen any presence of Minutemen in any libertarian organizations, though (I’m not denying that some Minutemen may choose that self-definition, much to our dismay).

By the way, I think the list of critical items where broad cooperation is possible can be lengthened a bit: in addition to the two you mentioned, the war on drugs, corporate welfare, and central banking. And there is currently a big shift in attitudes taking place within the libertarian movement regarding intellectual property (especially among ancaps), so I’m hoping that can be added to the list soon.
