total nudity is in relation to reputation to being as a good human for many US Americans.
Of course there is also some value in your proposition but saying that a society is totally shameless yet keeps cultural norms very high (like USA with nudity) does contradict the initial claim. It's something else then.
I get what you are saying. Perhaps its a morphing of what exactly people find shameful is the thing OP was talking about then. Where he identifies a lack of shame, its really just the shame is concentrated on completely different actions, and it makes the culture seem strange and wrong to a person on the other side.
