Well of course they weren't. A bit of objective inquiry on the net would rob you of that line of bizarre thinking or even the local library. Nazism is placed squarely where it belongs, on the far right and at least neo Nazis don't shy away from it, in fact they embrace it for the most part. The graph that JR put up is just laughable. One man's biased concoction that has no bearing on reality. Slavery is neither a conservative or a "leftist" thing so that's some more ignorance on your part. I can understand why folk on the far right really don't want to be associated with the likes of the Nazis, it's more than understandable but them's the facts. Unfortunately there are some traits that are all too similar in terms of what some propose should be enforced on society as a whole.
