alt Hacker NewsIt is true that modesty is not an exclusively US puritan ideal, but the US has a disproportionately strong cultural influence on other societies.
In my neck of the woods we are much more relaxed about nakedness, and find the scandals in the US around this topic amusing. But for instance the lengths at which for instance facebook goes to to avoid nipples and penises feels more like an overstep in cultural freedom.
Facepook is just another textbook example of bureaucracy breaking loose. Companies that give them money (for ads) declare that “content” (i. e. everything that exists in this world) can be “SFW” and “NSFW”, and they only want the former. Ergo, women don't have breasts. End of story. All the excuses and exceptions corporate human robots invent afterwards are just irrelevant icing on the cake.
It would be fine to just ignore that stupidity, but people who spend time in that hellish environment adapt to it, and actually start to believe that there is some deep meaning to the rituals they have to make, and even invent their own explanations.
