sorry my point being that the majority of Japanese karate possibly could have been driven by the understanding that UKE techniques were blocks, as perhaps they wernt shown the actual meaning - or perhaps it didnt suit the reason and 'standardisation' that karate went through to make it essentially a Japanese BuDo to fall in line with Judo and kendo.
it makes far more sense to me that the okinawans didnt tell the Japanese rather than the Japanese didnt tell the western world, of course a massive generaisation.
