Not at all. Just criticizing his blanket statement, apparently used to justify "doubting the results of US elections": "doubting" just for the sake of doubting, particularly when it feeds into narratives being driven by trolls, disinformation and hidden agendas, doesn't do Democracy or Truth any service.
I'm going to go ahead and assume that the people in question (that are doubting the results of the US elections) are rather "skeptical" towards (so called) mainstream media, but not as much when it comes to the random crap on fox news, ann, youtube and facebook. If this is the case, then this makes them more "useful idiots" than actual "skeptics", in my opinion.
TL;DR: "Doubting blindly" (usually based on whatever Fox News or 4chan is spreading today) is as at least as bad as "trusting blindly".
