I called Krugman a retard, a while back, during a discussion with friends.

One of them, who's very deep in the bubble said something along the lines of: "Are you really telling me that you know better than a professor of economics? Enough to call him the r word?"

Of course, I doubled down and said Krugman is completely retarded.

When I hear that guy talk, he gives me the same vibes as Peter Zeihan
