The problem with a concept like "decency" is that it's highly subjective and everyone has a different idea of what is or isn't "decent". Ultimately, the only person who can really define what that is or is not on this site is the owner, who has bequeathed that power to his minions...er....Mods. I believe that, for the most part, the majority of the Mods and Admins do a pretty good job of squelching the stuff that is WAY over the top and let most of the stuff that gets posted here fly. Their rules are really pretty simple: no nudity and no swearing. Other than that, they are pretty tolerant of most topics, language and images, even if some are in bad taste and some Mods are more tolerant than others.
The reality is, no web site, television channel, radio station, video game manufacturer or musician OWES any parent a clean, sterile, safe environment for their kids to play in. It is the responsibility of the parent to investigate and monitor the things their kids are being exposed to and decide whether they want them involved with those things or not. If you think a place is inappropriate for kids to be at then DON'T LET YOUR KIDS HAVE ACCESS TO IT! Demanding that anything censor and change itself to suit what you believe your kids' level of naivety should be is WRONG and horribly draconian.
