So you are saying that it is more likely that she was saying something positive and respectful while she was being rude and disrespectful of the moment?
Rude and disrespectful is a powerful claim, I would say it just follows along with her lack of grace in the public eye.
So if you calm down that rude & disrespectful portion of your question, then yes, I agree with what you are claiming.
I sincerely doubt everyone else looking in did not have a similar awestruck feeling. It’s just that Michelle was on camera.
