Although traditional martial arts (TMA) has deep history and tradition, it's not as practical as it used to be. From a self-defense point of view. Nowadays people are looking at a gun, issues are not settled the same, even when compared to 20 years ago. Also take in the account of mixed martial arts (MMA), you have a totally different breed of fighters. A person taking classes at a place that offeres wrestling, bjj, boxing, muay thai, will do better defending themself against an attacker than a karate/tae kwon do practitioner.
