What you see here is isn't some sort of neo-Nazi propaganda; rather, it's Christian propaganda.
I try not to be too hard on the Christian urge to evangelize. I appreciate the fact that their world view tells them that humanity is trapped in the metaphorical equivalent of a burning house with only one exit and that they feel that it's their moral duty to try to rescue us from that conflagration. Viewed from that perspective, evangelists and missionaries really are trying to do something moral, never mind that the rest of us get awfully tired of trying to be pulled from a burning building that we don't believe actually exists.
Be that as it may, some methods of evangelization take such absurd forms in their attempt to "reach" people that it's nearly impossible not to point and laugh. A particular egregious form of this is that of Christian comics. I have no doubt that we're all familiar with the works of Jack Chick, but Chick ministries aren't the only ones who've attempted to spread the word of Jesus through crappy art, stilted dialog and plots that a pre-schooler should find simplistic. A lesser known -- but still weirdly fascinating -- company is Spire Comics who ran a line of Christian themed comics such as the above "Hansi: The Girl Who Loved the Swastika" -- about a girl who initially loved the Nazis but eventually came to love Jesus -- as well as many others including quite a few surreal Archie Comics cross-overs.
I found a good fan site that has PDF versions of many of their comics. If you like reading Chick tracts (for a suitably broad definition of "like") I'm sure you'll enjoy reading these as well.
