I think the danger point is when she shows awareness that her anger excuses her from consequences. It confers upon her a kind of cultural immunity that justifies whatever she wants to do to any man in her life: sexually assault him, make a false allegation of sexual assault against him so that he will be imprisoned, murder him, verbally abuse him, torture him. A man's anger is evidence of his base brutality; her anger is evidence of her fundamental righteousness. Feminism has worked very hard--and unfortunately, has been quite successful--at implanting these twisted semiotics of anger in Western consciousness.
