Personally, I think the target audience here is dwindling and dwindling. In the past, people may have questioned and responded to this sort of delusional spin, but people have also had four years of Trump admin to see what actually happened and four years of Biden to see how insane the Marxists are, and now - I think - the audience that someone like Deniro can actually reach and convince is smaller than ever.

Because its so clearly delusional. There is nothing historical that supports his narrative: Hitler, a clown? There was at least 8 years of violence, political terrorism and upheaval before Hitler consolidated power. In hindsight, there was a track record that is clear. And the same with Mussolini.

Comparing Trump to either of these individuals is just what Deniro does: acting. Fiction. A narrative attempting to acquire gravity by force of emotional appeal (fear, dread, etc) instead of facts or evidence.
