Under no pretext should arms or ammunition be surrendered; Any attempt to disarm the workers must be frustrated, by force if necessary.
This was one of many quotes from Karl Marx that I feel a lot of folks don't know about that would change their perspective on him. There are a lot of people who decry Socialism as the anti-American devil, when in reality, true socialism is closer to their political stance than traditional religious conservatism.
Karl Marx was a staunch supporter of arming the people, to enable them to rise up against their government, which at the time was beyond tyrannical. And during his life he did so much work to make that a reality. I've seen a lot of the gun crowd make remarks that we need to send a shipment of ARs(freedom) to Hong Kong to arm the protestors there to fight back against their government. To them it's little more than a joke, but during his life Karl Marx acted. He supplied money and weapons to the armed resistance in Brussels during an attempted uprising there around 1848.
Instead of promoting the idea that the people fleeing oppression in their home countries should be greeted at our border at gunpoint and marched into cages, he put his money where his mouth was to aid them in taking their country back.
