While I'm sure he's very capable and very much an expert in his field, I don't think he's this charming super politician that planned an elaborate scheme to sway the conference attendees' opinions by appearing to be sensible and calm in front of hecklers.

I mean, can you imagine how horrible this would have turned out if he didn't stay calm? It's basically standard procedure to stay calm and try to explain your way out of it. Sure, he got some applause, and the heckler got some applause too. I think anyone could have imagined something like that happening.
