Urmm...
Well, the language is generally the same...the problem is those of us who don't curse very well

; The way I learned to curse, there really wasn't a big distinction between those two...I'm just as likely (in fact, more likely) to call male friends "little bitches" as "bastards". The more general problem is that there are only so many ways to be insulting in English. Unlike English, Japanese doesn't have as many set "bad" words...it's not a one-to-one thing. Most of the time, Inuyasha and/or Kouga (the ones who 'curse' the most) are speaking with verb forms that are insulting or "speaking down" to their opponent, and the insults they use are rude, direct forms of the pronoun "you". Unfortunately, that sort of thing just doesn't exist in English. You can't conjugate the verb "give" impolitely, nor do we have verbs that exist solely to show contempt for someone else. Thus, it falls to the writing to get across exactly how rude or angry they are being. Sometimes we will just go for an aggravated-sounding sentence--it's not appropriate to translate *every* instance of 'teme' as "bastard", for example. Likewise, sometimes it's not appropriate to dumb down the translation using softer insults like "jerk". (I highly doubt Inuyasha would call Naraku a "big meanie"

) The only word we try to stay away from is "f*ck", because that epithet would feel VERY strong in most situations...at the very least, it would be a BIG jump from the "softer" curse words like "bitch" and "bastard". If we use that word, rest assured that it only would be for a very good reason. The "shock" factor works better then, which is the main reason you use curse words in the first place. If they weren't good, crude intesifiers we really wouldn't use them. Even so, the overall policy is that the writing needs to convey just as much of the meaning as the curse does: if you use curses as a crutch all the time, you won't end up with decent writing in ANY language ^_~
But yeah, it seriously hadn't struck us as that weird to use "bitch" at guys...we'll be more careful about that in the future.
