>> While I agree with you on the idiocy of Mr. Andrews' statement, as a point of fact, the National Socialists in Germany were not atheists. <<
I think an anti-Christian nihilist fits reasonably in the broader term, "atheist." I know many atheists dispute that definition, but I think such dispute fits into the fallacy, "No-one in my group can do anything wrong, because if they do something wrong, they are not in my group." It's akin to Protestants disavowing the Christianity of the Crusaders. (Although the Crusaders saved Christianity, but I won't get into that argument.)
I also recognize that atheists have tried to argue that Hitler was a Christian. It's plain he tried to convince ignorant, nominal Christians that his ideology had commonality with theirs, but this would be like calling Mohammed a Jew. Hitler's anti-Christian comments are numerous enough, as well as comments stating the necessity for such deceptions, that they can be easily dismissed.
