This is something that I have never really understood. Why does the color of the thing you wear around your waist, change who you are as a person?
Sure, you had to work hard to get it, and it represents a certain level of skill and understanding... but, there is no consensus on how hard you actually had to work, what your skill level actually is or what your understanding actually is. Each art, each organization, each school... has their own levels set for each of these things.... and they are all subjective. This means that you cannot compare one black belt to another, based on rank alone.
I find it a little amusing and a little sad, when I see people demanding to be addressed by their rank.... in the grocery store.... Is the whole meaning of your life tied up in the color of the belt you wear? I also find it a little sad when the color of the belt contributes to the amount of truth or the amount of correctness a statement has. When we were both blue belts, we could talk and exchange ideas about techniques, but now that I have advanced to green belt... my ideas become more correct than yours.... really? And the whole "I now outrank you" bit.... WOW... from otherwise grown adults..... Its almost like all of their self confidence comes from the number of people that must defer to them, due to the color of their belt. And some of these people are not model members of society??? You don't say....
In my opinion, you can only do one thing with respect.... the only thing you can do with respect, is to give it. You can not earn it. You can do whatever you want.... but none of that means that I will respect you, unless I choose to respect you. You can make me fear you sure... but that is not respect. You can demand my respect, and show me the things you did to earn my respect and show me how much respect I owe you... but you look very silly when you do that, and I promise, you will not get my respect. When I find people, who are of right character, I choose to give them my respect... not because they asked for it, or deserved it... but because I wanted to give it.
But, we just have to find ways to build these little societies, where we can finally get the respect we "deserve." This is not something only found in martial arts... try going to ballroom dance studio.... There are lots of things we do, where we can then feel like we have done something to "deserve" respect and then go about demanding that respect.... and many times we forget all about the boundaries... and start expecting that same "respect" at the grocery store.... Whats really funny, is that we then criticize other groups and other people for doing the same thing we are doing, because they do it differently, or we find them hypocritical (why should I care, if you are hypocritical, shouting your principle of humility and then not being humble in the way I think you should be humble? The only thing I get out of that is making myself feel better...)
I say train hard. Be who you want to be. And let others be who they want to be. There is no universal black belt mentality anymore than there is no universal bar that every black belt must meet. See people for more than just the color of their belt... in fact, ignore their belt, and treat everyone as a real person. But I guess that makes me a little hypocritical now doesn't it.... Anyway, I just think we put way too much importance on belts than we should. At the end of the day, if we are talking about martial arts... its not your belt that has to fight... its you.
