I like it how the average joe says yeah, i take martial arts cause if someone ever insults or threatens me im going to tell him i dont want any troubles and then if he attacks me im going to dominate him and make "justice" !
Lol 9 times out 10 they keep shuting their mouth, getting harassed just like they were in the past as long as the bully/thug is bigger than them, and one day they find someone who is smaller, drunk, and finally practice some shit move on him and feel like they have finally become men. Until they re secure enough to try that shit on a real oponent, get their asses whooped and then suddenly convert to a peaceful religion or "decide" to focus on something else, like building pyramids with matches.
To be honnest it's only useful to repel a single aggressor but you also better know how to run fast, and for people who work in police, security or military. For most people yeah, it's just a joke. I love the asian or white/black "masters" (bullshiters) , they always make me laugh , they re just running a business and all businesses are based on someone else naivety. Also what is the use of knowing a martial art in a society where physical violence is banned. It is also useless in no go zones, ghettos etc where real thugs , maffia members have guns and knives.
