If you are so disgusted with the quality of MA instructors in your area, then quit. That's your choice, and no one here can - or will - stop you. You have said repeatedly that that is your plan, and I have no reason to disbelieve you. However, I do not expect that you'll find people here who are going to quit on your say-so. People start training in a martial art for a wide variety of reasons - including the one you give for yourself - and they continue or quit for an equally wide variety of reasons, most likely several reasons per person, and it is possible, although, in my opinion, unlikely that you will find someone here whose reasons and experiences are sufficiently similar to your own to cause them to follow your lead simply because you are convinced that you are right.
I am convinced that I am right - but I am convinced on my own behalf - and I neither want nor expect people to follow me in my choices simply because I say so - no matter how much experience I do or do not have, and no matter home many times I reiterate my reasons.
You've made you choice - good for you, you've made a choice; that's more than many people do - and I mean this sincerely, without a whiff of sarcasm. If you truly want to stand out from the crowd, follow through on it. But don't expect to convert people to your choice for the reasons you've given, and don't expect people to suddenly agree with you in droves, as I find that unlikely.
