People keep bringing up nazi propaganda as if it's a serious threat, but is it? The most successful radicalization stories I've heard are about people being recruited into ISIS. The political echochambers that have the most reach are the censors at Google and the campuses they graduated from, stemming from the cult-like application of progressivism. The most pressing issue of science illiteracy is climate change denial, pushed by capitalist interests.
People are worried about the one ideology we are most inoculated against, and for which tens of thousands can be whipped into a frenzy to protest against, _even if no actual nazi event is taking place_. This is not a real issue. Neither is being upset that you're letting your kids be babysat by bots who make Sims machinima. If the author feels there's a flood of dangerous content out there, why is the article full of milquetoast embeds?
