I agree that that old military firearms do carry some of the symbolism from their former owners.
For me, my German K-98's represent the failed country that we defeated. It's a symbol of our victory over Nazism.
My East German Makarov, that I bought surplus for $100, is another artifact from a failed country. To me, it's a symbol of the victory of Western Capitalism over Communism that happened in *my* lifetime.
I remember the Berlin Wall. It was up before I was born and I never thought I'd see it come down in my lifetime. The fall of the Berlin Wall, and what it represented, was one of the defining moments in my lifetime.
I don't have a literal piece of the wall. I do have that East German Makarov, which, like the wall itself, was a tool of the oppressors.
My ownership of that pistol gives me great satisfaction. The wall came down, the west won the spoils, and that pistol is a symbol of our victory to me.
If other's feel different, I can respect that, but I don't feel that I have to agree with them (or they with me).
