Ahem... Pokemon is QUITE FOR KIDS EVEN IN THE ORIGINAL!
It's about time to do some research...
-the roughest Pokemon ever got was Legends of Dratini where Team Rocket actually fired a gun but misses anything... in comparison to Gundam Wing who got 5 nameless pilots dying every episode...
-the original copy of "insult" is something like an insult, yet not enough to be swears... one must take note that whenever you're translating a show to another language, you can change how severe a put down is... Look at it like this:
the sentence is: "________ you, you infidel!"
Now there's at least 5 words that fits in that blank, and a lot of words WILL work for that blank... ranging from swear, to "curse you", or even "Away with you" and all of them will make sense in terms of context. Yet it's a lot worse when we use swears in the blank, in comparison to the other terms which are much nicer.
Plus, you shouldn't be swearing regardless of kids show or adults show... it's just needlessly rude to swear. Plus it really shows your lack of self control or intelligence when you have to resort to swearing... especially in an arguement.
