Correction: American studios only edit series they think appeal to a kid friendly audience. Series like One Piece and Naruto really had no chance of ever being acquired unless they could gain an audience that would support a TV run. The reason is because both series have licenses that require a big investment. Both are too cartoony to show to teens and adults so companies that pick up these licenses do so intending to show them to children in order to guarantee a return. Unfortunately, you can't show blood and gore to children on TV in the US so edits have to be made. Plus most kids don't usually care if the main character is named Ryuu or Ryan so usually names are changed so the kids can relate to them. While it sucks for fans that have knowledge of the series, companies have to guarantee a return on each series they invest in, otherwise there wouldn't be Anime or manga period in the US.
All fans can really ask for is uncut DVDs in the end, but they pretty much blew that when both the uncut versions of Yugioh and Shaman King didn't sell well. So in the future, it isn't going to financially sound for companies to bother with uncut versions of series they acquire for the childrens market. That's why I don't see the US ever getting an uncut version of One Piece, but Naruto may stand a chance if people apply some pressure to Viz.
And in reality, American versions aren't near as bad as some series that have been released in other countries. The Latin American version of One Piece faced worse name changes and edits and while I don't remember them at the moment, other series have faced edits worldwide. Just depends on the culture of your country.
That's old news and YES it's true...the americans seem to have a skill to f**k anime and make it a dumbass version because they aren't able to just TRANSLATE the damn anime
