Tangentially - being an edge case doesn’t inherently dehumanise someone, edge cases do exist and we need to be able to discuss them without feeling we have to deny that to protect people.
I've read an anecdote somewhere that some phrenology doctor tried to find the most average man in a camp, by measuring everyone and then finding who is closest to all averages of measurements. Turned out that no one had all their measurements near average, everyone was off in one category or another. So, most of us are edge cases.
