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)
There are a lot of things we should be doing as a society that we aren't and spending time advocating for stricter gun control is not high on the list. Obviously we can champion many causes at once, but encouraging those on the US 'left' (because you're not convincing conservatives) that guns need more barriers will ultimately lead to a group with less means of self defense that is more easily targeted by increasingly violent chuds
The United States absolutely needs gun control, gun control for cops, gun controls for whites, guns in the hands of the lgbt and Black populations, and out of the hands of second ammendment nutjobs.
