Here's the Nazi response to the propaganda that the Nazis didn't celebrate Christmas. From the fantastic "Everybody's Hitler" from the fantasticker German Propaganda Archive.
Hitler's enemies lie when they say that Christmas has been abolished in Germany.
This is the truth: Hitler had thousands of Autobahn workers as his guests in the Berlin Sportpalast at Christmas 1938. Note the Christmas trees. Hitler celebrates Christmas with his soldiers, next to a decorated Christmas tree.
