I don’t want to keep spending time on this. My position is that QAnon is a fringe internet phenomenon that is a total unknown to most people. Of the people who do have some knowledge of it, few take it seriously. A few crazies do, sure. But its somber elevation to grave significance by the liberal media is totally ridiculous (and gave it more attention than it ever would have gotten otherwise).
