Actually one of my former students is a Wumao and I asked him about it. He feels he is doing is duty protecting China and as to those that dont like him (as a wu-mao) he says basically that those are either sellouts or that they are lie "misguided Children" who need to be brought back. He is rather hard core and will no longer watch any movie with Jet Li or Gong Li because they are "traitors" for having given up their Citizenship.
