I’ve only known one guy with one of those and he was one amazing man.
All brave men who survive tyrants have my respect.
Lost a good friend a few years ago who worked for my father-in-law. (in the weapons industry) I became acquanted with him at family gatherings he attended. His father immigrated from Lebanon, Lebanonese Christians. The son was a WWII vet and served in some capacity in the Balkans and in ME after WWII. Very well read man, and spoke Arabic. He and I found we had a lot in common as far as interests politically when visiting during the family gatherings. Found out later, part of the common attitudes was that we were both Masons.
I have never known a survivor of one of the concentration camps, but my father was at Dakau 2-3 weeks after it was liberated. He later oversaw a group of German prisoners who cut timber from the forest around Munich for heat that winter. What he saw in Europe forever changed him. When we talk about it, I can still see the emotions well up in him.
You should have seen the expression on his face when I showed him the “Obama Children Sing For Change” video. He had seen that before in Germany. The Hitler Youth.
