My greatest surprise with these reddit SJW leftists is that none of them truly appreciate how useful the United States military would be in achieving their goals. For all of their talk of US imperialism, ableisms (seriously, they'll ban you for using the word "stupid"), and hatred of strong states, the only way that a world wide socialist order could ever emerge is if the US military and police were co-opted over time by hardcore dogmatic leftists and overthrew the government in a coup and began conquering the rest of the western hemisphere.
Honestly, these guys might not even be communists at all. We're probably looking at the result of the "new left" that formed in the 1960's out of the Vietnam anti-war movement and general hippie antics. To take the point further, I know a PKK, a anti-state Kurdish communalist militia, member (a practicing Sunni if I recall properly) who has openly advocated hanging gay people for being deviants. Can anyone imagine how our internet communists would react to such a social conservative? They'd blow a fuse trying to figure out whether to ban him for wishing death upon homosexuals or praise him for fighting the Turkish government and ISIS.
I also have to wonder where these idiots believe that they'll be doing in a socialist government. Are they really all highly valuable workers like engineers and doctors who will likely be spared in a revolution purely out of practical necessary? How many Communication majors does a socialist state really need? (the correct answer is zero for those wondering)
No, as others have already said in this thread, they'll be the first to go to the wall. If for no other reason than because they wouldn't shut up about mass executions or simply take the bribe when it's offered to them.
Personally, when I look at r/latestagecapitalism, I see a bunch of sad depressed individuals who don't have the common sense to band together, form a political party, and campaign for what they want within the system that already exists. For all of the flaws of the United States, you can always start a grassroots movement and use (possibly illegal) methods to ensure your election to various government offices. Or maybe that's the real issue, none of these people want to put in the effort to create the world that they so desire. They're just lazy buffoons who got dealt a bad(?) hand in life and don't want to take the necessary steps to correct it.
