He's basically talking about Godwin's Law[1], which reads: "As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches one." and "Any off-topic mention of Hitler or Nazis will cause the thread it is mentioned in to come to an irrelevant and off-topic end very soon; every thread on Usenet has a constantly-increasing probability to contain such a mention." The TL;DR is that whatever you are saying isn't worth anyone's time of day if you're using Hitler or the Nazis in your argument, and you made everyone in the room dumber with just your sheer presence by doing so.

If you prefer less modern examples, see also Reductio ad Hitlerum[2] which was noted in 1953 by Leo Strauss. George Orwell also observed it in passing in an essay in 1944.[3] [2]: https://en.wikipedia.org/wiki/Reductio_ad_Hitlerum https://en.wikipedia.org/wiki/Reductio_ad_Hitlerum [3]: https://en.wikipedia.org/wiki/Fascist_(insult) https://en.wikipedia.org/wiki/Fascist_(insult)
