I had actually emailed Lt. Col. Grossman about this some years ago. His reply - lost in a catastrophic hard disk crash - supported my main contention. He really did believe that people could be categorized that way. And there was a strong cop/soldier as sheepdog bias.
Again, with all due respect to the work he's put in, he is still wrong. People are capable of being aggressive, of defending and of being passive. under different circumstances. His typology is still emotionally loaded. It is still inaccurate. It still implicitly denies the possibility of regular people taking self-protecting actions under extraordinary circumstances without violating type. Given his extensive work in the field it is hard to reach any conclusion except that he had an unspoken agenda. My guess is that he was going for the law enforcement market as his post-Army work has largely been in speaking and training law enforcement.
