I used to date a girl that had basically grown up in the antique shop that her father owned. It was amazing - we would watch Antiques Roadshow and she knew what everything was and almost exactly what the experts would say it was worth every time. After her father died she ended up with a ton of stuff in her house, and one day I went over there to find she had put up an "Ein Volk, Ein Reich, Ein Führer!" poster from the 1930s featuring good ol' Adolf above the fireplace. She wasn't pro-Hitler or anything, just thought it was an interesting bit of history. I was like "babe, c'mon, we want to keep our friends".

The opposite is kind of weird too. My late Jewish father was absolutely obsessed with the Holocaust. He had virtually every book ever written on the subject. There was a room in the house my mother and I called (much to his chagrin) 'The Holocaust Room' because of the vast number of books on the Holocaust there were inside it.

He did have sort of a reason for his obsession. He was in London from age 7 on through the war because his parents didn't evacuate him and he spend the years 1939-1945 waiting for the Nazis to invade and put him in a concentration camp. So it made sense to me, but it was still going pretty overboard.

He saw Shoah more than once. It's 566 minutes long.

It's the same as gay conservatives.

You don't want to overthink it else your brain explodes.
