Well, I can't speak for anybody else's obsession with uniqueness ['cause I can't get in anybody else's head] - but for myself, it's being considered a misfit and tending to be an observer-of-groups rather than a participant-of-groups. I *do* seem to have some connection to other observers-of-groups but never felt the "pull of group" with them, but rather, a fondness. Best I can think of at present. Sense of clanlessness = individual = uniqueness. Of course I'm not clan-less. I'm part-of many Clans. But that 'something' always escapes me with regards to most groups.
