Yes, Mentzer recalled the episode:
"Here was this big Prussian son of a bitch disrespecting a bodybuilding legend. We were all shocked by how arrogant and debacuhed Arnold's attitude was. I confronted him about it, and he cowered."
Poor Mentzer; he simply didn't have the genetics to beat Arnold. I personally admire his precise, logical approach to bodybuilding training. But the thing is, I suspect, that he took his obsession with Rand and objectivism too far. He bacame excessively logical, and started to believe that Humans relate to each other through objectivist logic; he actually believed that mind games, manipulation and favoritism are not parts of Human interaction. How could he win the title against a man who, although he had retired previously, was, coming into the contest, a six time Olympia winner, and who defeated him on both muscularity and natural structure? Poor Mike...

Also, Arnold is a natural alpha male: a man who was born to rule. It's obvious that Arnold's ability to play mind and political games was superior to Mike's: Arnold completely and utterly dominated all the men around him, through a combination of intimidation, false flattery and outright deceit. Mike never had a chance. The fact that he publicly criticized Weider and his training methods, on magazine articles, didn't help him either to win Joe's most important contest. Mentzer was a great bodybuilder and a brilliant intellectual, but he was a social retard.
