its not the product, its the end user
agreee, being a flexible martial art aikido is depending on the practitioner in applying the art. although two people comes from a same art the outcome can be different.
In my personal opinion aikido is not bound by 'violent' or 'soft' alone. Aikido gives its practitioner more option to deal with his/her attackers compared to other martial arts. depending on situation and mood, a soft aikidoka can turn violent on certain situations and vice versa. Besides, what does 'violent' mean here? Is it the Steven Seagal style aikido, or when a person attacks you you just avoid and let him bang himself to a wall?, both of them can be considered violent, I think....
