I'm in the mental health field. I see this type of thing every day. When an individual wants to escape responsibility, let's say for hitting a fellow patient. It might go like this: "Bob, why did you hit Andy with that stick?"
Bob's response is "Joe, why did you hit Andy?" Classic avoidance of guilt and/or blame. Classic schizophrenia.
So - Beyonce, why are you stealing all those -creative song writers- songs? oh I see Sasha Fierce is doing it.
