What's the point of a war movie that is scrubbed of the very reasons war is a horrible nasty thing? That would be like Titanic where there's enough lifeboats for everyone. Oh wait, somebody actually did do that...
I don't care for people who curse loudly and in public, either. (And my Dad swore like the sailor he was. I curse quite a bit when nobody is around.) But you can usually avoid a book or movie if there's questionable content. Ratings these days are so detailed, they practically give away plot points.
Books don't have ratings of course, but reviews can probably clue one in as to content.
Fan edits are like dance remixes. They require a certain amount of creativity and passion that's lacking in something merely being edited to appeal to a segment of the audience who can't even handle the mild profanity allowed in G rated films. Anybody can censor a movie. You don't even need a pair of scissors these days.
This app would be more fun if you could at least replace the dirty words with suitable replacements, like kumquat, but it would probably censor that as well. ;)
