I agree with everything you've said.
That's why, as you say in the last paragraph, I commented on Beau's enthusiasm for that guy in the videos.
Not sure I follow you. When you say:
I don't see anywhere how this helps anyone.
It would be interesting to see what think the child in Africa watching the video on a mobile phone with his parents' income of 100 dollars a month.
It seems pretty at odds with trying to see how Beau's points could very well be good insights. Your tone seems less 'rigorous devil's advocate playing' and much more 'dismissive and overtly cynical'.
Regarding the idea that if there's nothing to say it's better to remain silent, I assure you all that I try, but damn it, sometimes I read something and think, "This is missing!"
But your tone suggests that because the information being presented doesn't quite fit all your frameworks, criteria, etc. - you give yourself justification, all too easily, for throwing out the proverbial baby with the bathwater. Also, being an STO candidate doesn't mean that the person in question is going to positively impact the lives of all people. Maybe that isn't quite what you were getting at, but can you see how what you wrote can be construed that way?
