1. Here I am using the colloquial meaning of the word propaganda, which is ideologically biased information, usually it takes the truth but then stretches it to breaking point and beyond.
2. I do not possess a Facebook account. I don't even have a mobile phone. I don't watch Fox News in case you were curious. I hardly watch any television at all since I don't have one. Many readers of Hacker News do not have them, it's a common demographic in geek circles.
3. Class warfare is a real thing. It is not an extreme concept, it's a descriptor. Europeans like me frequently complain that Americans don't grok class or that Americans conflate 'race' with 'class'. You don't have to agree of course. Perhaps America is the one nation on the planet that didn't gradually evolve a class system as it matured ;-)
Humour aside, I do think this (gradually evolve a class system as it matured) is one of the major reasons why many American intellectuals are increasingly interested in old European ideas and books from the 18/19th centuries. Their resonance is much deeper than it used to be.
