I don't know, but . . .

Althouse noted that one of the "performers" in an old exhibit at MoMA was suing. I'd heard of the exhibit some time ago--it sounded "modern art" level stupid. A gallery door was partly blocked by a naked man and naked woman, and visitors had to "squeeze" between them to get in. There was another entrance to the gallery, but I assume there was social pressure to "experience the art."

The man is suing the museum on the grounds that they did not protect him from groping--sexual assault. 14 years after the fact seems a little late in the day to complain, of course, and thus there seems to be reason to doubt his sincerity. But there might be another way of looking at it.

Just as clothing communicates things to other people, adults being naked outside of specific circumstances (doctor's office, group showers, etc) communicate sexual interest. So the situation is intended to be a sexual one, albeit with some implausible deniability ("This is ART, you fool!"). And if the man and woman are so close to the visitors that one has (remember the social pressure) to make contact with them, this seems a bit like unwanted sexual contact: a sexual assault.

It seems a bit unusual for an "assault-er" to complain about reciprocation. Although active groping does ratchet it up rather more than a notch.
