you are absolutely correct lasaire, i think i just worded what i wanted to say in very crappy way...sorry =/

but i actually meant something different. i think genjutsu is just a branch off from ninjutsus. or other way around. or even, nin and gen are branched off of the ability to use chakra. taijutsu doesn't require chakra so it's in a separate category whereas nin and gen are chakra based.
