Earlier quoted context omitted.
I don't know if you've ever been to Europe, but the number of topless beaches are low and you won't see women walking around without a top on the street. It's not taboo-less, nipples are still sexual. Nipples seems a pretty silly thing to start focusing on when he clearly said they weren't interested in adult content.
I'm from Europe and I've visited quite a few countries in Europe, and to me it seems like it's pretty normal to be topless on _any_ beach... Spain, Portugal, France, the Netherlands, Greece...
EDIT: Generally I'd say in Europe while women's breasts are sexualised, they're not considered sexually explicit. The US is exceptionally prudish in comparison and for well-known historical reasons, too.
