I know we all love to criticize older generations, but in the 20th century if someone did a Nazi salute you could almost guarantee that a WW2 veteran would punch them in the head, and I think there was a great societal benefit to that.
My dad laughed that he didn't serve in Korea because he was 4f from a badminton accident.
He's probably pissed off in hell that he didn't get to live to raise his arm with pride. I found Nazi shit when he died in 2015.
PTSD is very bad these days.
