Considering America is awash in guns, I don’t think it should be surprising. In the early days of the republic there were many armed uprisings... Not to mention the US Civil War.
The violence around protests has had remarkably little to do with guns, except maybe for police shooting protestors. A tiny handful of events when huge protests are taking place in basically every city is itself pretty remarkable.
Belarusians have a lot of hunting riffles on hands too. But these are tightly regulated. You can't wear it just because you want to. And people were jailed for possession a single WW2 era round found in the forest (Belarus had a lot going on on its territory during WW2 and as the result - a lot of stuff is still in the soil all across the country).
