IIRC, you started out by asserting that MPDGs actually exist — that’s where I had to break with you. They exist only to the extent that we impose MPDGness — our fantasy — upon real people, and it’s more than a small burden.
In the best of all possible worlds(!) we would each recognize our own potential, and not feel the need to be coaxed into doing what we already want to do.
We create MPDGs, much like gods, in our own image. It’s not a quality inherent in a person. But we need to recognize that people are messy and love is difficult.
