i just feel that the subbers are being more coarse
unless they actually do say words on the same taboo as "forget" in children's cartoons
I was watching the Japanese "Kirby: Right Back At Ya!" with english subtitles, and there was quite a lot of swearing. I believe I saw the word 'bitch' in one of the episodes or something like that, but mostly it's ass, crap, damn, and hell. Still had the japanese equivalent of a TV-Y7 IIRC.
