I seriously doubt that many modern MA-ists live their lives by the code of Bushido. Remember, Samurai (a less accepted term in old Japan) literally means "one who serves". Americans & other industrialized people are too "entitled" to serve (they want to BE served). This attitude is contrary to Bushido.
How many of you have argued w/ your boss, parents, sempai etc.? Unacceptable for Samurai.
How many of you would die for your boss even if you knew he would provide for your family?
How many of you would kill another person (right or wrong) on the order of your boss?
How many of you would kill yourself by disemboweling & decapitation for bringing shame upon your company resulting from a mistake?
I'm sure there might be members of special forces that have chosen this way of life but to the rest of us, it's simply a romantic notion, fantasy @ best. There's no room for "individuality" because then it changes everything - from "others-centered" to "self-centered".
To me, you might as well pretend you're a Jedi fighting the Dark Side - it's just as valid.
