For anyone who saw the flagged comment: I found this: Scott Adams has questioned the methodology behind the figure of 6 million Jews killed in the Holocaust, suggesting it may not be as well-documented as commonly believed. However, he does not outright deny that the Holocaust occurred, stating that "no reasonable person doubts that the Holocaust happened."
There's no much difference between the two positions, and the former is very much a lead-in to the latter.
He has a lot of weird anti establishment takes. For example, that evolution isn't real [1]
I'm not 100% on the reasons. Seems like he simply has a lot of hubris.
