Wallace,
Thanks for sharing your thoughts and questions.
Unfortunately, there aren't any formal mental competency rules for president, as I pointed out five years ago: https://dockruse.medium.com/adhd-trumps-behavior-military-ironies-22148aa1fe4b
and as we have witnessed in the last week.
I appreciate you pointing out the role of society in determining what is right or wrong, healthy or good. Others have said that our failure to respect and include a diversity of brains in our society is a reflection of a sick society, not sick individuals.
