I apologize if I was unclear, I didn't mean to say you hid your criticism, but that if you wanted to expand the conversation instead of contract it to a topic you found unsuitable, you could've expressed yourself differently, eg, by saying, "I don't see a reason to believe that, but even if that were true, wouldn't it still build capacity?"

You're free to express whatever however, but you expressed dissatisfaction with how the conversation went, so I was just offering my perspective on how that came to pass.
