Hmm, OK she has featured violence in her movies, but there's still no reason to assume that she's pretending to be a macho or anything similar... otherwise I'm affraid I don't get your point.
It's important to be aware that a person aspiring for filmmaking is always going to pass through a fase of experimentation and discovery in it's earlier period of activity.
As time goes on and more works are created, experience builds up and the output will become clearer in it's style and intention, more refined.
Honestly I can't see what's so special about Kathryn Bigelow treating about violence just because she's a female...
I could probably direct you to other films featuring violence directed by females as well.
One particularly cruel and heartbreaking film set in the context of WWII from a russian female director comes to my mind, can't remember the names right now... it's a damn good film.
I believe this director has prominently used violent contexts in her films as well.
Also using a number of quotes of unknown sources looselly describing the plots or synopses of her films doesn't really tell much either...
Without actually seeing all her films it's impossible to make any sort of claim about what is her true cinematic language or ideology/political agenda.
EDIT: The film I was talking about is called "The Ascent" (1977) directed by Larisa Shepitko. Her ouvre is actually small because, unfortunatelly she lost her life in a car crash when she was 41 old. I highly recommend seeing this movie it's great stuff!
