If its indeed true on what OP had observed on that debate, then it feels like fielding an inexperienced and weaponless soldier into a war where the enemies are veterans and have adequate firepower to demolish on those who will stand on their way! I guess we all know what will be the outcome with that kind of scenario!
I think it might be better if the crypto-community would pre select our own crypto ambassador(s), who have adequate knowledge in all things related to cryptocurrency and blockchain technology and its benefits in economics, finance and other related industries that might benefit from it - to represent us with those kinds of events and face these naysayers defeat them in a convincing matter! Imho.
Sorry for posting it too late.
