As with any style there are other elements that make up our training that are native to and that have been "borrowed" from other systems and that can be used effectively as self-defense...we share a common history of sorts. For example, a side kick is a side kick and a punch is a punch. I agree with the sentiment that it is not about the art itself but about the artist. In addition, not all martial artists train for self-defense either, some train strictly for the -do...and this is not unique to any one style.
