Nerdiness is an expression of trauma. Pain in our lives leads us to recede into areas of interest. These can be things that "fix" us or things that we are naturally good at or become good at. Its all therapy to feel better about ourselves. Everyone has trauma and everyone is a nerd in some area. Aggression is projection. When lashing out we chose areas of safety from which to do it. Thus people who have been hurt chose to be aggressive in their areas of expertise. Boom fierce nerds.
