Re: unfair belt rankings
You're the rank you're at, regardless of your belt color. It's really not that important. There's nothing unfair about your sensei shaking up the colors a bit. It's not as if you've been demoted.
The ever changing belt color drove me nuts when I was doing karate. Not only in terms of the ego that gets attached to belt color but also in terms of what it did to my wallet. I was a very poor college student so coming up with the money to both pay the exam fee and then buy a belt was a struggle, especially if I wanted to, you know, eat more than bread and peanut butter that week. Belt colors are pointless. You can tell more or less where someone is in their training just by the way they move.
