You're assigning motives to me that I don't have. Maybe that is the distinction, you think how you appear to an audience is important, I'm viewing this no differently than I would a private conversation. I'm not performing or signalling to anyone.
This really isn't the same thing as an interview. I'm not talking to you for the benefit of an audience or as a way to document your thoughts. I'm saying what I think and responding to what you think (and accuse me of thinking). I'm expressing my own opinion, I'm not trying to win a debate or make myself look good.
