Seriously? Have you ever listened to an earnings call for an exchange-traded company? The analysts absolutely destroy executives during the Q&A sessions on a regular basis. Being an executive involves being thick-skinned and rational.

If you are seriously entertaining the idea that FC avoids the forum because he's scared of a little criticism, you desperately need to re-evaluate your confidence in him. "He doesn't post because he's too busy to ever check in" doesn't sound great either, but it's a lot more palatable than "he's too scared of the trolls".
