Assuming that aikijujutsu was intended for use in war: simply asserting a lineage doesn't endow something with the virtues of its forerunners. Vaccines are derived by weakening more destructive pathogens but I don't consider an MMR jab to be useful as a biological weapon.
I agree with all of this. I was asserting a lineage to show how aikido fits a term, that's all. My point did not extend beyond semantics.
