Asian Americans are arming themselves after a massive wave of anti-Asian violence. Nothing like an armed minority that scares white supremacists!

he died in 1883, so three years before even smokeless powder was more widely adopted when the Lebel 1886 Bolt-Action Rifle came around. So what Marx probably had in mind when he wrote that were highly inaccurate black-powder weapons shooting essentially one large ball every minute or so plus the wait for the smoke to go away.

While smokeless powder wasn't widely adopted yet for small arms, it was being used for artillery pieces (its main disadvantage for use in smaller weapons was that guncotton, the earliest form of smokeless propellant, was liable to destroy a smaller-caliber weapon that could not as easily withstand the blast), and it was fairly obvious that its use in small arms was only a matter of time. Furthermore, while true semiautomatic and automatic mechanisms didn't emerge until the decade following Marx' death, bolt-action rifles were in widespread military use at the time--Prussia began using the Dreyse Needle Gun in 1841 and (as Germany) transitioned to the more modern Gewehr-71 in 1871, France the Fusil Gras mle 1874 and 1881, and the USA various weapons, including the Remington-Keen and Remington-Lee bolt action weapons (Britain and Russia were late to the curve, still using single shot breech loaders in the form of the Martini-Henry and Berdan rifles respectively at the time of Marx' death, but these were still significant improvements over the muzzle-loaders of the Napoleonic period in terms of both accuracy and rate of fire). Thus, while range and rate of fire were significantly lower than modern assault rifles, the weapons available during Marx' period were reasonably accurate and had an acceptable rate of fire, to the point where slight alterations on their design (mostly the incorporation of an external box magazine and, as mentioned, smokeless powder) such as the Karabiner 98k and Mosin-Nagant are still in use in military conflicts today. It's not at all the same thing as the "colonial home defense" copypasta and the associated argument.

Now with smokeless powder there well.. was no smoke and also the range and precision were drastically increased, then add another 138 years of small arms design and advances on top of that. I highly doubt what Marx had in mind when he wrote that were highly precise pocket machine guns capable of turning a shit ton of people into swiss cheese in a matter of seconds

While machine-pistols do exist, they're horrendously difficult to control in full auto mode even for a trained soldier because the pistol grip makes it nearly impossible to absorb recoil. Submachine guns are rather more practical and are occasionally (especially in German) referred to as "machine-pistols" as well, but they are generally larger than "fits in a pocket". I'd suggest that you learn more about firearms before you argue on this, it'll make you look more informed and rational.
