That's nice, when did I say or even imply that there was no yelling in 'all' martial arts. I took TKD in my youth, and dabbled in Karate, I know they yell and in my many many years doing this stuff, I have seen all sorts of styles that yell....but they all do not...and in your limited experience you apparently were not aware of this and I based this on this post that you had made
I simply listed those that do not yell and pointed out you can find them in virtually all cities. And traditional Chinese martial arts, all Chinese Sports Sanda/Sanshou, all Chinese Police/Military Sanda/Sanshou., most Aikido classes, virtually all JKD classes, they do not yell, and there are more...... apparently did not know this..... now you do.
And you are posting on MT and even though you may yell in your martial arts class, there is no need to yell when you post and large bolded letters are taken as yelling.
