I really think there's no specific fallacy or deeper philosophy behind this. It's just that there are various random idiots talking crap about stuff they don't understand and they occasionally stumble on to a platform to raise the profile of their stupid ideas.

I think the general sentiments motivating and bolstering particular piece of BS are "I wish things were simpler", "I don't trust big organizations", "I want people to pay attention to me", "I don't care about the consequences of what I say."

On the other hand, I suppose there is a general populist trend which encourages a site like slate to give thoughtless immature authors a platform for their stupid ideas as long as they stroke populist themes.
