As I said, I have a bunch of examples - but I'm not going to list names here.
In any case, if you're content with an organization that treats Japanese and non-Japanese differently then that's fine - but many people are not.
I'd note that the long time to shodan in North America isn't mandated by Aikikai hombu - that's a decision by the local North American instructors.
Sorry, I missed it when you mentioned you had a bunch of examples of people being clearly discriminated against. If I knew first-hand of some kind of unfair treatment, I suppose I would be more passionate about the issue.
I don't expect names (obviously), but I'm curious if these are examples where the people in question clearly deserve the title but are denied it for some kind of personal or political reason that you know of.
