This is a (literally, in this case) "performative" narcissist waving a colored cloth around as if he were somehow striking a blow against "genocide", instead of just indulging in self-righteous attention-seeking. He should be fired.
His objective was not to do or accomplish anything useful or effective, but merely to cadge accolades for how "stunning and brave" he is. But I have more respect for those "Just Stop Oil" assholes who obstruct traffic. At least they're placing themselves in some degree of jeopardy by pissing people off. It's stupid and does their cause no favors, but at least they're putting something on the line for what they believe. What's this guy doing, apart from being an exhibitionist masturbating himself in front of a crowd that probably mostly already agrees with him?
