I think there's two problems with the query:

  1. You probably want "FILTER NOT EXISTS", not "MINUS", to do what you want. See: https://www.w3.org/TR/2013/REC-sparql11-query-20130321/#neg-notexists-minus
  1. Note that wdt: would capture only preferred ones if there's preferred one. So if you want to capture all subjects, not only preferred one, use p:P921/ps:P921.

With these corrections, the query seems to work fine.
