It's not just about parenting, many people (myself included sometimes) view the site during downtime at work. In my workplace, I doubt if anyone is "prude" or offended by human nudity, but as a matter of common professionalism, I avoid all nudity-flagged threads when at work. Now the babes in undies in the banner ads, pretty hard to avoid, LOL, but I'm not complaining about that. Use of the nudity tag is more than just a requirement, it's a courtesy for all sorts of reasons.
