A title is necessary if you want to become a teacher / Sensei especially if you want to living from the Martial Arts
Nope
But the title say nothing about your skills (about 20 years ago I as a 2nd Dan Taekwon-Do challenged a amateur boxer with NO titels for a full contact fight and beat me in 30 seconds....)
A title is just that a title and it does not necessarily mean a thing.
There is nothing wrong with earned titles, emphasis on EARNED. Do the time do the training and if someone calls you Grand Master, Master, Sifu Sensei, etc. that is ok with me.
What is not ok are those that insist upon it whether a governing body has given them the title or not. Or those that are angered that a student calls them teacher or Mr. or master and corrects said student with "That's GRAND MASTER" or if one day a guy shows up and say I have been training my style for 10, 20, 30 years or more so now I'm a grand master. These are the titles I have a problem with.
Personally when I taught and if I teach again my students call me by my first name. All of my CMA sifus have been called by there first name and my Yang Tai Chi Sifu has been doing Yang Tai Chi and only yang Tai chi for somewhere around 45 to 50 years and all his students call him by his first name, except for a few of us Traditionalist types that call him Sifu. And he refers to his teacher as Sifu and his teacher's teacher as Sifu and as far as my style goes if anyone was going to be called Grand master it would be his Sifu (Tung Ying Chieh) and his Sifu’s Sifu who was Yang Chengfu. The only title I have ever heard, other than Sifu applied to Yang Chengfu was Old master by one of his few living students.
But with that said if someone where to call Chengfu Grand master I have no problem with it. If the guy down the street with 5 years in Tai chi who knows Yang 24, 48 form and a wu form and has been to a couple of Chen family seminars insists upon it I have a REAL problem with that.
But think of all the real long time Martial Artist out there, how many actually call themselve Grand Master.
EDIT: This thought just hit me. It would seem that if one insists that they be called Grand master that they feel they know all there is to know about their martial art and therefore they have nothing left to learn. To me this is actually rather a sad thought.
