I agree it's not crazy. To me the best explanation is that Facebook introduced many inexperienced people to political topics, and they had trouble distinguishing fact from fiction. Someone told me something similar happened when radio first got popular. Hopefully our societies will get better at filtering information as these technologies mature.
It actually does make me wonder if we can see a connection between what's happening now and what happened when Protestant Christianity started spreading with the whole "priesthood of the believer" deal where everyone can read the Bible in whatever translation and interpret it just as well, supposedly, as those who are trained in Greek/Hebrew/Latin and actually studied the historical context of it. Seems very similar, in some ways, on a rough look.
