I suspect the person is an actual communist and not one fond of dictators? no? :) . I still stand by the idea that real communism as professed by Marx can't survive in groups bigger than the hunter-gatherer groups of old for much more than a generation before it will self-immolate. Most people are "greedy" and will only truly sacrifice for their loved ones like family and their "best of" friends. I will dive to push my child out of the way of an oncoming vehicle without regret or pause (or at least hope I would) and would stand back in a similar situation happening to a neighor and hope my neighbor "survives that" or ponder "that's gonna hurt"
