I never quite understood the hubub over words... a world is simply a given collection of sound(s) composed through various "vocal" apparatuses, which are given meaning by the context of the dialog and the resulting interpretation of the word by society, the latter part being the key factor. Society at the present time determines what the word means and translates to, meaning that words are superfluous and almost meaningless relative to the overall duration of time.
In other words, words are just words, their meaning changes with time and society, thus the adage actions speak louder than words. Actions are more concrete and less changing (at least in terms of interpretation and meaning) than words, making them more ideal in most situations, especially to some.
I see no problem with douche.
Just like ****** has two meanings, as well as bastard, bitch, etc. They all have their respective origins and meanings which still hold true (to those who know them) this day; thus I support the lack of censorship desired by some.
Case and point; look up the urban definition of ******ing versus the "real" definition of ******ing.
And to those who don't know what the asterisks translate to, hint: its a bundle of sticks.
