Fox News is problematic, may be even extreme (Sean Hannity et al) but I would not put them in the same league as InfoWars. At least not as long as Shepard Smith gets airtime there.
If we are to complain about Hannity, then we have to include Maddow. Assuming we are trying to be intellectually consistent. She’s just as “extreme” but from the other side.
Classic false equivalence. You are right that Maddow is similar in style, but on a fact-to-fact based comparison, Hannity is some orders of magnitude more extreme.
