Nice work trying to keep an open mind and rebut their comments.
They are big guys with big voices and i feel like sometimes you had to fight pretty hard just to get a word in. I hope everything calmed down at the dinner and you were able to relax and enjoy the night. I will shoot you an email about the next BeyondBitcoin hangout (i was waiting for you to do this as it was advertised as your First Talk).
I can promise you a much more relaxed and open environment with some smart and passionate people open to hearing about the news, advancements and goals of all projects including Bitcoin.
