I can't believe the words are coming out of my mouth, but you are putting Adolf Hitler to shame. The fucker lived to despise other cultures and races. It was his entire raison d'être. He hated people; that is simply what he did. He hated Jews, blacks, Slavs and gays. He hated Muslims and Native Americans and Asians and Roma. He hated other European groups like the British. He hated those with mixed cultural heritage. He hated liberals and socialists and atheists and especially communists. He hated miscegenatiors and race traitors, Jew-sympathizers and Indians. He hated Aboriginals and Pacific Islanders, he hated Australians and Kiwis, he hated the Maori and Latinos. He barely brought himself to tolerate the Japanese and lily-white Argentinians.
Am I missing anyone? Oh, wait, he also hated Jehovah's Witnesses and put other cultish religious minorities to death too.
By the way, UHM, it is commonly believed that slavery was not the cause of the civil war. Indeed, there were a few other factors. However, that is like saying that the Hindenburg's barely flammable skin, and not the seven million cubic feet of Hydrogen, was the major cause of the conflagration. Not only does it hopelessly, disproportionately exaggerate factors that may or may not have been involved at all, but it discounts the overwhelmingly important cause of the event by belittling it with a comparison to factors so minor as to be nearly inconsequential. By saying that slavery was "just another straw," you're basically ignoring the fact that it was 98% of the problem.
Slavery caused the civil war. Period. No further explanation is needed. Because slavery was so hopelessly entwined in the southern economy and culture, it is literally inconceivable what the south would have been like without it, ergo it is pointless to argue that other social factors that were caused by slavery were more important than slavery itself.
