Not that finding out that liberals like segregation in 2006 would prove anything about the righteousness of the Northern cause in 1861...I just want to see if you're actually capable of citing a source.
Since you're responding to a post in which the subject is race, you should be reminded that in 1861 the "righteous" Northern cause consisted strictly of preventing secession. At least that's what Mr. Lincoln said, and who's to argue with him?
Fat chance of that ever happening.
