Justin Gaethje threatened to beat Dave Portnoy during an exchange at UFC 282.

Dave Portnoy: “Gaethje talks shit about me for supporting Paddy. I respond by saying it may be hypocritical to throw stones when people are saying he hung around with a brutal dictator (Ramzan Kadyrov) a few weeks ago. He threatens to beat me up.”
