You tell me. I copied the letter from Freeman's biography of Lee. Are you saying that Freeman is biased?
[thee] You tell me.
No, you tell me -- you guys used the word "betrayal". I want you to explain to me how General Lee's letter supports the notion of "betrayal," as in, "Benedict Arnold" or "Vidkun Quisling" or maybe "Anthony Blount".
Demarche, I'd believe. "Bad idea," I'd believe. "Poor policy," or any number of synonyms -- after all, that's what Madison, Washington, Franklin, and others thought of disunion, and even federal union. They wanted a centralized state. They didn't get it, and the actions of Lincoln's faction in 1859-60 in using the wedge issue of slavery to unite the North for a permanent factional takeover of the national government showed how prescient the old Patriots had been, in their misgivings about so-called "federalism" done Hamilton and Madison's way.
Ein Volk ein Reich! hasn't been America's style, ever. It's the burden of statists and corporofascists like you, to explain why it's good for us, even when we're just policy objects anymore, and seldom listened to.
