When it comes to the UK, I think the BBC has tended to give a false impression of our country’s attitude to nudity over the years. The other channels have, at various times, experimented with shows including nudity (with mixed success) but the BBC has always been very unkind to those shows.
The average attitude to seeing nudity in the UK is much more accepting than the BBC would have us believe. Unexpected nudity often doesn’t cause outrage and distress.
