Well I would ask, where did your child learn about all of these things?
Because in the real world its very rare to come across these ideas. To me it rings, Tumblr and these online chatting websites. As well as online games.
Do you have information and should your child see a therapist? It's probably necessary.
edit: and I don't mean to be mean. heh.
Origins, and Identity is a struggle, it can be a knowing and a feeling that you dont belong, stressed by the yearning to be accepted.
