Which of these (former) countries' symbols is it acceptable to display?

In light of the rally in Charlottesville being inspired by the removal of Confederate symbols, I'm curious which of these countries with less-than-stellar reputations you would not judge someone negatively for displaying.

I'm also curious, since I have some Eastern bloc memorabilia. Despite the awful systems in countries like Ceausescu's Romania or Stalin's USSR, it doesn't seem like buying a button with a red star or a pocket watch with a hammer and sickle on it has the same sort of emotional effect on people that a swastika or a Confederate flag would. Plus, I think a lot of propaganda can have some amazing art value and tell you a lot about the country that used it. So, I feel like I'm at least a bit more torn about the whole Confederate statues issue than other liberals, even though I think on balance the symbols should go, or at least be relegated to a garden outside some visitor center at a battlefield or something.
