The point of projection - according to Freud's study of psychologically dysfunctional people in Victorian England - is to defend a person from his/her own awareness of his/her dysfunction.
e.g.
A fat woman I saw at a clinic in Glorietta Makati - who saw then 40-year old still sexy Carmi Martin walk by - contemptuously called Carmi Martin fat blissfully unaware that she is actually describing herself.
