Yes and No, I will break it down to you like this as taught at the dojo I train at. First form of self defense is to not put yourself into a position where you have to fight. IE don’t walk down dark alleys late at night, ignore insults, walk away, or if you have to run away. This covers just about 99% of situations. If the 1% happens then you fight until the threat is ended using every means available to you.
