Are you talking about people in the USA or people elsewhere in the world? The USA is always “special” when it comes to matters like this.

It’s definitely not just an American thing.

“Under no pretext should arms and ammunition be surrendered; any attempt to disarm the workers must be frustrated, by force if necessary.” -Karl Marx

America codes have a “unique” culture around guns, but that’s not all that prevalent on the left. What’s driving interest in guns is the sad fact that we might need to use them.

The thought process that “we might need to use them” is evidence that the left in America does think about guns differently than the rest of the world.

You should mention that that was Karl Marx before the US civil war. Not Karl Marx in an age where drone-based warfare is common.

Are you suggesting we build weaponized drones?
I’m saying that if Karl Marx had written things in 2025, what he would have said would undoubtedly have been different than what he wrote in 1850.
But the need for workers to defend themselves from the capitalist system/state has never been more pressing as the capitalists are once again choosing fascism. I doubt Marx would be advocating for disarmament in today’s world.
The need might not have changed, but the option to use weapons to do so might no longer exist. OTOH, in Marx’s time communications technology was primitive, there was no way to coordinate instantaneously with other people was limited to people who were within earshot. Maybe a 2025 Marx wouldn’t talk about giving up weapons, because he’d know taking up arms against a state was pointless in 2025, and instead he’d be all about mesh networks and encryption.
