Hail the confederates!

I am currently reading Grant's memoirs and there are a lot of great quotes. This one from his view on the Mexican war which he opposed, but thought that it should be fought to conclusion will all vigor and support once it had begun.

Experience proves that the man who obstructs a war in which his nation is engaged, no matter whether right or wrong, occupied no enviable place in life or history. Better for him, individually, to advocate 'war, pestilence, and famine,' than to act as obstructionist to a war already begun. The history of the defeated rebel will be honorable thereafter, compared with that of the Northern man who aided him by conspiring against his government while protected by it. The most favorable posthumous history the stay-at-home traitor can hope for is oblivion.

He is right. Today the confederates, despite fighting for the most dismal of causes, are hailed as brave heroes fighting for their country. Take Robert E. Lee for example. He should be considered the greatest traitor in American history. He took an oath to defend the constitution! And took up arms against his oath. Instead, today he is hailed, while the war opponents in the north are now despised and disgraced.
