It's probably a daft question. But I've come to know from reading many articles that 3k karate is seen by traditionalists as some kind of commercial inferior westernised and sanitised version of karate. But until recently I'd never even heard of '3k karate', and still don't really know what the term means. Google seems to suggest it is kihon kata and kumite. But I don't get what's wrong with that, if that's what it means.
