Bubbles,
It was Nazi's that were fighting Christians. Nazism is a religion in and of itself.  It took symbols from different religions, even the Indian  'swastika' did not originate with Hitler but 'eastern mysticism'.  How do you like that?  The most prominent symbol of the Nazi's had nothing to do with Christ, His Church or Christians. It was atheistic and believed in the super 'man' of Nietzsche. No, it was not a Christian organization at all.  It was very much anti-Christian and evil.  To become a Nazi was to reject Christ. Still is.
