Further, it's worth pointing out that the people painting the nudity were not Vulcans neutrally painting "just what reality is" either. The painters set out to push certain buttons with those paintings, and the fact that people react is a measure of the fact they succeed. It should hardly be a mystery that people have further responses to the fact certain buttons are being pushed; indeed, it would be a mystery if they did just consider it no different than a painting of a bowl of fruit.
We can, however, train ourselves to pass more control on our forebrain and, like you mentioned ("painters set out to push certain buttons with those paintings"), those paintings were a very important tool to measure the success of that. When there is this dignitary empowered to act on collective behalf, it's only comforting to find out that he holds enough self-control to act cool and rational, that he is competent enough to deal with whatever social play, including the basic instinct attempts, without compromising whatever public business he's out to solve. Given the context, this pampering only unsettles me!
Who has the most thoughtful, the "right" "model of human minds" between those who commissionned these works, those who produced them and those who veiled them today?
The original article didn't exactly come out and say that they found the whole thing mystifying, but I've seen enough similar things that it seemed relevant, and I do think that's the general tone.
Besides, the same type of nude art works, were produced long before (even in prehistoric times), east, south, north, and west of the Mediterranean sea.
IMO, it's simply religions creating a totally artificial prohibition to create relevance from thin air.
This is all about the strange and disastrous new European fear of offending Those Who Must Not Be Offended. In this case a visiting Iranian head of state, but we see this stuff played out all over Europe every day, from this level and all the way down to minor, personal encounters.
But please, let us pretend we don't.
No it's not: The article describes several examples of such censorship, none of which had to do with Muslims (which I guess you're alluding to).
It's not a surprise, these things are cyclical, and global culture went through nearly 50 years of expanding tolerance - The drug use of the 60s and 70s, glorification of teenage rebellion in 80s and 90s, and the tech disruption of the aughts. We're seeing a resurgence of spirituality, in much the same way we've seen it before[1]. Not all of it is explicitly religious, some of it is just indistinguishable in it's goals.
There seems to be a certain alpha male - or at least alpha authoritarian - model of power which is rooted in a pretence of stern, serious, and disciplined public morality combined with private self-indulgence.
When you have naked boobies on display in public buildings, that model of pretended integrity starts to break down. Boobies and naked bodies - especially female bodies - are fundamentally antithetical to the immensely serious business of public alpha moral posturing. They're strictly for private off-the-record consumption only.
Non-authoritarians don't care about keeping up appearances in this way. But authoritarians and narcissists most certainly do.
