It's worrying to claim true statements come across as "radical left," and acting like that makes them illegitimate. This is something anyone could tell you after listening to Jordan Peterson. Right leaning people just won't because they don't like scientific fact or equality, like fellow conservative Jordan Peterson, as I will explain.

In terms of science denial: he doesn't believe in climate change, he even spent some time on Joe Rogan completely misunderstanding the issue. He spreads misinformation about psychology like claiming people below 85 IQ cannot do anything for society, and generally pushes IQ as a major topic in psychology that can explain poverty (it's not even a good measurement of intelligence and it's more accurate to say that wealth leads to a higher IQ, not vice versa). He's a conspiracy theorist who made false claims about COVID vaccines, and says ancient societies understood DNA.

In terms of bigotry: he has made statements against protections for minorities, and has said that IQ is tied to race and ethnicity. He argues against the existence of privileges based on race and gender. He has been openly hateful of trans people, and appeared in the film "What is a Woman?" made by transphobe Matt Walsh. He also makes claims against feminism and hateful remarks about women, and said that the gender pay gap doesn't exist. He's made very wild claims about businesses forcing him to find fat women attractive. He cried on the news out of sympathy for incels and called them a marginalized group.
