It would be more true to say it depends on whether they are a statist or a libertarian. There are plenty of northerners who recognize the truth.
Interesting issue--one that I haven't seen before--but I haven't met many libertarians who believe it's ok for one man to own another man.
Nice strawman you built there -- you have to be either a statist who cares nothing for individual rights or a libertarian who only cares about individual license and to hell with everyone else.
Thankfully the Framers saw it differently when the created a Nation of laws under the Constitution. Lincoln did no differently in 1860 than Washington would have done in 1790, nor what any patriot President would do today. That is, preserve the Union under the Constitution.
It's the statists like Obama who care nothing about the Constitution and the spoiled libertarians (apparently you and others here among them) who want it their way or no way without regard for the Constitution, who are the problem.
Why don't you try Conservatisism for a change so that you can leave something worthwhile for your kids?
And apparently some who wouldn't recognize it if it bit them in their Jefferson Davis.
