Hitler was a fan of islam and said if it was not for his atheism, he would have been muslim... which sounds eerily similar to where liberals stand.
Also he cursed the catholic origins of Germans and wished they had been muslim instead. He pretty much planned implicitly for a replacement of Germans by islamists... so much for his followers thinking he had their best interests as a socialist
the rap against the germans here is not a rap against germans persay but a rap against Atheist communists—of whom the USA has quite a few. They all want to destroy western civilization and replace it with a pharaoh state—just as Islamists want to destroy western civilization and replace it with a caliphate.
