>>20543408OP is not a black belt in anything.
OP probably got beat up by somone.
OP is coping because he is a skinny fat loser who can't fight.
OP thinks that martial arts require specific clothes and ground to perform.
Also knowing martial arts and not knowing them makes you equally stabable so its better to know them if yknow, they don't have a weapon.
In short OP is retarded.
Don't be like OP. Be better, do martial arts.
