It always bothers me when clubs push self defense like crack when advertising their clubs. Self defense is something that has to be specifically taught. It isn't just a side effect of martial arts training, especially because a lot of places that claim to teach "self-defense" don't do any practice with resistance or have 110 lb girls practice on other timid 110 lb girls.
This has recently been on a my mind because of the women's self defense class that takes place before my taekwondo class. What they are doing in that class is not self defense, and it's just down right dangerous that the university is allowing this individual to push elbowing and kneeing someone running at you with a chest protector like it's self defense.
In any case, definitely a tragedy.
