At least your first assumption( “Seems … a covid denier”) is false.

He is one of those scientists who was all for it, got the jab, promoting masks. The whole lot. Educating the masses with whatever FDA and WHO were putting out. When the publications started telling a different story than what we were told to believe he chose to follow the evidence… (around this time he changed his background poster) In one of his video’s he genuinely apologized for science missing the mark, and that thus he was misinforming the masses by it. His backdrop now says “follow the evidence…”. Also, If he would be a covid-quak, youtube would have censored him long ago by breaking youtube guidelines.

i wonder how many more people were downvoting(not saying it was you) without an idea what it’s about :/
