I'd get rid of all the self promoted "shihan" "soke" "8th, 9th 10th dan" nob-jocky we have floating around discrediting Aiki as a whole.
I may well be narrow minded (and I make no apologies for that) however, when it comes to credibility, I don't see a "live and let live" philosophy. You are what you earn. Simple as that in my book.
Guess how many 8th dans we have in the UK.
Guess how many of those are from independant Org.
Guess how many of those came from Japanese sources.
