German historian and author Dr. Rainer Zitelmann is currently under criminal investigation in Berlin for retweeting a meme comparing Putin to Hitler. He's one of the world's leading experts on Hitler and National Socialism — and the tweet was a historical warning about dictators who say "just this much, then I'll stop." He faces up to three years in prison.

Lou and Rainer dig into Germany's Section 86a speech laws, government-funded neighbor-reporting hotlines that echo the Stasi, how cancel culture has escalated into legal repression across Europe, and why the laws designed to stop neo-Nazis are now being used against historians, libertarians, and center-right journalists.

They also get into Rainer's new book New Space Capitalism (Skyhorse Publishing) — the case for private property rights in space, how SpaceX transformed an industry that 50 years of government programs couldn't, and why capitalism is the only system that has ever actually worked.
