William H. Stoddard:

[The Republican Party] also has moved to big government, denial of Constitutional rights by presidential [fiat], unbalanced budgets, fiscal irresponsibility generally

Well, you know, all that’s not really anything new for Republicans.

I read the platforms of the dozen Libertarian candidates who got onto the California ballot (not including Paul, Barr, Gravel, or Ruwart) and I only thought three of them were remotely credible as libertarians; the rest included some conservative Republicans trying to claim the libertarian label

Indeed. As much as I despise Bob Barr, I actually have to say that he’s not the biggest tool in the LP race. Unfortunately, I can only say that because his competition happens to be Wayne Allyn Root.

VRB: Why is Lincoln singled out when millions of lives had been ruined under all the presidents until then, even the ones that libertarians honor …

I can’t speak for libertarians as a group, but I am a libertarian and I can’t think of a single President of the United States that I “honor.” I happen to think that all of them were perfectly repulsive, and those who preceded Lincoln deserve special contempt, both for their ongoing use of Federal bayonets to enforce fugitive slave laws and protect Southern slavers from uprisings, and also for their repeated forays into ethnic cleansing and genocide against American Indians. Other libertarians, especially those who are minarchists rather than (like me) anarchists, might be somewhat less sweepingly harsh. On the other hand, they’re also likely to be somewhat less harsh towards Lincoln in particular.

However, the reason that Lincoln’s under discussion at the moment, rather than every other President in U.S. history, is that the post is about secession and the U.S. Civil War. Since Lincoln was President during the U.S.’s largest-scale secession crisis and during the U.S. Civil War, it makes sense to discuss Lincoln, but going on about how I loathe and despise most or all of the other Presidents in U.S. history would have been somewhat off the topic.

Jason,

Just so we’re clear, I certainly didn’t mean to suggest, in setting up my hypothetical, that I was under any delusions as to the motives of Lincoln or the other Federalis in the U.S. Civil War. I’m well aware that the liberation of the slaves was not in the least a war aim, at least at the beginning of the war. Part of the point of the abstractified hypothetical was to make an a fortiori argument: if anything could justify the reconquest and occupation of the South on libertarian grounds, it would be the liberation of Southern slaves. But the liberation of Southern slaves would not in fact justify the reconquest and occupation of the South, even if (contrary to fact) that had been the cause that the Feds went to war for. Thus nothing could justify the reconquest and occupation of the South on libertarian grounds. (There might be a legitimate case for something different — such as the use of armed raids to liberate slaves, when not followed by conquest and occupation — but what it might justify is different from what actually happened in the U.S. Civil War precisely to the extent that it doesn’t involve any attempt to forcibly override white Southerners’ decisions to secede.)

To the extent that the Feds engaged in a brutal war and occupation, killing, maiming, and ruining millions of people in the process, for reasons that had nothing to do with the liberation of Southern slaves, I think that that makes the Feds’ position that much more repulsive, and obviously indefensible.

As for the rest of your discussion, it’s interesting, and deserves a careful reply, but the reply will probably take more space than I have here. Perhaps soon, on my blog.
