I recently read a comment where the author said he did Tae Kwon Do for self defence and to protect his loved ones. How does Tae Kwon Do, do this?
The World Health Organization estimates a third of women in relationships are beaten. According to the US Justice Department, two-thirds of violent attacks against women are committed by a man they know. The FBI says 2 million men beat their partners every year. The greatest danger to 'loved ones' comes from inside the home.
In the online magazine 'Bloody Elbow' an article appeared which contained interesting information: "Christy Mack held back tears as she voiced those harrowing words on HBO's critically acclaimed ‘Real Sports with Bryant Gumbel.' She recounted the disturbing tale of her ex-boyfriend, former UFC and Bellator fighter Jon Koppenhaver, as he allegedly brutally beat her to the point of convulsions. Using public records as their main resource, Real Sports determined that the national rate of domestic violence arrests is around 360 per 100,000 men. On the same chart, they contrasted that against NFL players, which found 210 arrests per 100,000, while MMA saw a staggering rise to 750." https://www.bloodyelbow.com/.../hbo-segment-domestic-violence-ufc-mma-christy-m...
Considering the practitioner wants to protect loved and statistically he poses the greatest danger: Does Tae Kwon Do teach practitioners not to beat up their partners? How? The same question would also be applicable to Wing Chun, Kung Fu, Karate, Aikido, Jiu-Jitsu, Judo etc.
NOTE: Although my solution has been to stop teaching adults as they all land up fighting or doing competitions, I believe there is a more generally applicable answer to the question. Long ago, after I had invited him to join Kyokushin, a mercenary told me he prefers doing Shotokan katas to calm down between 'missions'. I cannot speak for Shotokan but it might be some practical solution like that.
