Last I checked, his audience was those self-proclaimed "intellectuals". The kind of atheists who define their identity by dunking on religious people, and the kind of mediocre people who feel superior by laughing others.
People who look at cherry-picked and out-of-context examples of progressivism and then dismiss the entirety as anti-science wokeness. People who cherry-pick scientific beliefs (without deeper research) in the same way most religious people cherry-pick passages from their holy text. Take the (out-of-context) quotes that reaffirm what you already belief in, ignore the rest, and most importantly: Declare that your "truth" is superior to others.
At least it’s not quite on the level of orphancrushingmachine stories the wholesomememes community was known for on Reddit.
