KiNgBrAdLeY7: Don't get me wrong, i love tradition and antiques, them being an item, a teaching, or an ideal. Yet, they are actually entirely useless? If you cannot utilize those techniques into practical protection of your person, or
retaliation against people that harmed you a lot, then, what would be their use, i wonder...?
You speak as if defending oneself, and revenge, are somehow equal?
One of the reasons laws exist in the first place is to cut the retaliation spiral that could easily ensue without them:
I called your wife ugly => you let your dog pee on my lawn in retaliation => I shoot your dog => you shoot my wife => I set your house on fire etc. etc. etc.
So the only "retaliation", or rather, compensation, you should seek should be through lawful ways (call the police etc.). That's how modern societies nowadays work. The main point of police and courts is not necessarily to compensate either party, but to cut the escalation of the problem.
Furthermore, you seem to have a very traditional view on martial arts. If you want to know how you are allowed to act on real situations etc., I suggest you seek non-competitive (and possibly non-traditional) martial arts classes which take local laws into account. For instance at least here krav maga and defendo tend to be such martial arts. At least in the KM classes I've attended there has been lots of talk about what is perceived as lawful course of action in different situations.
That's why e.g. when someone someone simply grabs your wrist, we weren't taught to instantly hit the grabber to the face with our free hand (and/or kick to the groin), which would probably be the simplest and most effective course of action in such a case. No, we are taught to get our wrist free from the grab, without striking.
It is both because it would not be lawful to strike someone for simply grabbing your wrist (unless, maybe, he was pulling you towards the bushes, or had a knife in the other hand, or it was otherwise apparent it is a dangerous situation), but also because quite often you wouldn't necessarily even want to strike him/her. What if he was your friend grabbing your wrist in jest, or your wife/husband, or your boss? You might want to get free without damaging the grabber.
Also, such martial arts take also psychological effects into account, e.g. how to de-escalate such encounters so that no physical fighting is necessarily needed at all. Hitting a wrist-grabber to the face could easily escalate the problem further, even if you were able to put the lights out on him (his friends see you hitting their friend etc.).
