Subtypes - Spineless (including avoidant personality disorder | features) @ Wikipedia

"Basically Insecure, bogus, Spineless, venomous dominance is counterphobic, public swaggering, selects powerless scapegoats, is diminished with group support

Cowardly and deeply insecure, the spineless sadist seems to be a target among the other subtypes of antisocials, these people have live in a world where there enemies powerful than they are, having delusions of vulnerability, hostile tendencies are then projected outwards on powerless scapegoats, in order to fall stool any future attacks, this gives a false image of self-confidence. The public swaggering is ment to be a message to others that he/she is not ment to be messed with. Its common to find these types of people in ethnic minority groups, or simply an obesed or skinny person."
