That's because White Supremacist's believe in a different "Jesus", a "Jesus" that was a Nordic warrior who was at war with the Jews. Such is even evident when Hitler once stated "Jesus fought against the materialism of His age, and, therefore, against the Jews." White Supremacist groups twist history to their own justification. Of course, if Jesus were to resurrect in their very own faces, they would be flabbergasted!
I've noticed, especially in the case of Adolf Hitler and others like him, is that there are inconsistencies within his speech. Adolf Hitler was by no means a Christian. He was raised in a Christian household, but that didn't even dent the slightest of his beliefs. Adolf Hitler believed he was a "god", and the Mein Kampf being the Bible. The whole "Jesus" act was just a folly act to dupe the multitudes into believing his crude, cruel doctrines.
I suspect that Adolf Hitler was Satan in Human manifestation.
