No offense meant to anyone, but I really do worry about the mental wellbeing of people who would choose to dump ALL their past photos. I can fully understand that one might want to thin them down to a few selected examples, and that those examples might not be shown to many people, but we are all in part the product of out past lives, and I worry that there is a horrible unreality and denial in the heart of those who cannot acknowledge that past.
Aside from the fact that it seems to me to be a psychologically worse situation than being pre-everything and in the closet, it also suggests that the person in question is in deep denial, and in all seriousness most mental health professionals would probably consider that to be a borderline psychosis. So I think this notion is actually dangerous to peoples emotional and psychological wellbeing. By all means lock them up and keep them very discretely, but we all need to keep at least a few to remind us of how far we've come.
Its an understandable temptation, especially in the euphoria of taking the final steps in your journey, but it really is a dangerous siren call which should be resisted if we are to stay healthy and rooted in reality.
