Hog, once your cortex gets used to having blood supply from use you'll find that many historical and political issues are related and share common threads of meaning that synchronously connect across diachronic time. It'll be like the scales falling away from your eyes. The original thread was about state's rights to seceed. States seceeded because of economic conflicts based on racial grounds, namely the politics of slavery. The moral and scientific justifications used during those times gave rise to the climate and thinking paralleled in America as related to their obliquely concomitant manifestation in WWII and recently in Bosnia, among other places. The same connections can be seen in the Pacific with other English colonizations; in the slavery and genocide of Tasmania for example: the list goes on. Slavery and the culture of racial superiority still had a profound influence in America up untill the Civil rights act (or, the liberal entitlement act as Limbaugh would probably call it) of 1964, and persist even today. Surely you're not so daft as to not see the connection? You think the crusades of the 13th century or WWII have no relation to European-America's actions of today in Iraq? This country didn't pop up in some parallel universe, it emerged from English culture, German culture (the refugees from the peasant wars of Germany in the 19th century), and many other still active etiological influences. Slavery and genocide didn't begin or end in America, but certainly played a major role in the history of our culture as well as the world at large, and still do. Look at the big picture, don't take easy refuge in the safe compartmentalization of a 'thread.' You have a very simplistic view of this issue as having arose de novo without precedent or consequence.
