> I understand that there was a civil war before, but doesn't secession make way more sense now?
No, it doesn't. The idea that basic human rights are of subordinate priority to sovereignty and something that we will just agree to disagree on has less currency now than in the 1860s; secession as a means of handling this kind of disagreement made much more sense then than now, and it didn't make a lot then, either.
So what's the strategy then? To be blunt, it doesn't seem to me like the US and human rights are going to have the best possible relationship in the next 10-20 years. Wouldn't it be better then to cut away from it?
