I understand what you're going for, but I think this idea would just reinforce the imaginary walls we use to group humans. The underlying idea is that X-people understand X-people, where X is some arbitrary group, but non-X-people lack the perspective they need. For example, we consider people with black skin to be a group, but not people with blue eyes, or people who can curl their tongues. Let's just work our way toward thinking people are just people instead.
