I think a lot of us have run into a guy like this at some time in our lives. Now what can we see here, other than that stock photo minorities are apparently very vindictive people?
Well, the most annoying thing, beyond being nagged to do something you don't really want to do, is that the speaker is basically blaming you, the audience, for not being enthusiastic about something as stupid as his initial greeting, or maybe a catchphrase he wants you to repeat later, or maybe some opinion you're supposed to get excited about.
Well, that's his job. He's supposed to get you excited by making the subject matter exciting, not by guilting you into pretending to be excited. Does the pizza delivery guy have the balls to lecture you about not paying him for the pizza when he hasn't brought you any pizza? Does he tell you that good customers pay money? Does he act disappointed in how little you care about the pizza he didn't bring?
