Hell, in the Power Records book and record sets, Sulu was drawn as a black man (while Uhura was a blonde white girl).
Takei was upset over the "don't call me tiny" line in Star Trek III, thinking the fans saw Sulu as some amazing hero. "They don't see Sulu as tiny." He totally didn't get it. He did admit he was wrong when it got a huge laugh (as intended), but it really points up that his ego is no smaller than Shatner's. If nothing else, it's larger since Shatner at least earned his!
His current 'internet fame' is probably doing nothing to diminish that too.
