Some do, no doubt, but some do not. This interview is an example of one who most definitely does not.
Traditional Martial Arts are not just focused on self defence. Students are also studying an art. Some students practising Traditional Martial Arts are learning self defence skills they would never have been exposed to otherwise. Some would never have sought out a self defence class or course. So this exposure is a great thing for people. Traditional Martial Arts is how I began on the path.
I asked Matthew Apsokardu to do this interview as I know him from his blog (and you probably will too), Ikigai Way. Matt has been studying the martial arts for 16 years and has acquired the rank of 4th Dan Okinawa Kenpo Karate and Kobudo of the Nakamura Shigeru, Odo Seikichi, Bruce Heilman lineage. He is a good guy who always offers some straight up commentary on matters I raise here on this site about violent behaviour such as knife attacks. He has also written some very interesting posts on his site as well that make for interesting reading. He is very experienced and knowledgable in the martial arts world yet still very humble.
