What is the fascination with Nazis? And why do people want to idolize Nazis?

14. Several reasons. One big one is period fascination.

The war cast a very long and dark shadow. Veterans had trouble letting go of the war. Their children couldn't understand their clinging to the past. These artifacts are a tangible reminder of a father or uncle(s) that one just could not understand.

The items on the OP's list were probably brought back a war trophies. A former neighbor had a house full of ordinance--German potato-masher style grenades, US pineapple style grenades, mortar shells, small-arms ammunition, 20 MM and on and on. He had the stuff displayed in plain sight. The pineapple grenade looked as though it had not been "safed" so I asked. He said no, everything was live. My children did not enter his house.

The night he died (in the hospital) his wife called the police dept to tell them there was ordinance in her house and would they please come and get it. She was not going back in there until it was gone.

Then, there are the White Supremacist and Aryan Nation knuckleheads who glory in this stuff.
