The exuberance argument is purely one of Occam’s razor, because the alternative explanation is that someone has conspired to act in a predatory way in front of potentially millions of people globally…you are essentially into the territory of psychopathy…the inability to feel shame.
The Rubiales incident has no features of anything that could at all be easily replicated for the reasons I give above, if a man kisses a woman in a predatory way it’s going to be be in a clandestine setting, most people even if they are willing to engage in such behaviour don’t have it within them to do it brazenly in front of countless people.
