During Trump's first term in office I developed a hobby wherein I would get hardcore conservatives to unequivocally support various talking points from the Communist Manifesto, normally in response to them bitching about "leftists". This takes a lot less effort than you might think.
I mean it's not like I told them they were agreeing with communist propaganda at any point during the conversation so from everyone's perspective in the moment everything was going fine. The typical workflow was something along the lines of them bitching about liberals which is fine by me until they misapplied the term leftist or similar at which point I'd normally inject a non-sequitur about how bankers and execs are piling up cash with a forklift while the folks that actually work for a living can't hardly get by. This never gets any pushback and provides the perfect opening to quote your choice of communist propaganda, which also doesn't get any pushback as long as you aren't goofy enough to attribute your sources. ;)
My favorite example is probably getting my wife's uncle to agree that the proletariat has nothing to lose but it's chains mid-rant about how right-wing militia groups are the only folks in the country with a finger on the pulse and how they were absolutely going to overthrow the federal government with a selection of canned goods and small arms...
