Rousey nearly twisted Meisha's arm off their first fight. Just one example of how wrong that statement is.
As to TKD: They use Korean so it is dojang instead of dojo. They proliferate because it is the soccer mom of martial arts. Most karate is as bad.
Judo does have atemi waza, it is rarely taught now. And was not for randori since it was deemed to dangerous.

Krav maga is the cross fit of martial arts. Krav and such give a false sense of badassery. Good Krav is rare, like good pick a flavor karate, good TKD, good pick a flavor Kung Fu school. Do them because it is fun, to learn about another culture, to get in or stay in shape. Any self defense capability should be considered ancillary. You have to pressure test the way an art like BJJ and judo does, against all shapes, sizes, skill levels, athletic abilities, to develop an effective skillset. Muay Thai, kickboxing, boxing, and full contact/knockdown karate that spar hard and often are great too.
Every retard with a pulse thinks they can punch you in the throat, kick you in the knee, gouge your eyes, fish hook, attack your groin, and stop you with their car keys. Try that against someone that throws 10 of thousands of strikes every year, spend 100s of hours on the mats and sparring, and endures through ass beatings and injuries. That is where you separate the players from the fans.
