By workers he clearly means labor unions. Individual people who are not engaged in the revolutionary struggle or the defense of communism should not have access to guns (or any weapon for that matter). Western leftists, particularly American ones, have liberal brain worms because they intertwined this with the second ammendment. Not everyone who is a worker should be entrusted with a fucking gun, the organizations that represent workers however should. Its the same argument with cars, are cars bad? Not inherently, but we as a society should be phasing them out. Western leftists listen to China challenge (HARD)
I think gun control in China works because the workers are in control of the state, the military is in serve of the party so there's no reason for individual workers to own guns. That does not mean there isn't guns in China. I'm just stating post revolutionary society should strive for gun control.
