I agree fully with those that have said that you need to be worried about your own improvement not who get promoted or what belt you have. No one suddenly becomes better after they get promoted in rank. One's skills are what they are regardless of their belt color. When you understand that you will make progress. Until then you are wasting your time complaining about who did and who did not get promoted. If you can't resolve this issue, then perhaps the martial arts school you are in is not the right one for you? OR, even more so, perhaps the martial arts is not for you?
Making comments about who is and who is not worthy of being promoted amounts to you placing yourself as if you are qualified to make such decisions. It is an insult to your instructor that you feel you know better then he does what should be done.
