point of view

Flying back from the UK yesterday I passed through Heathrow Airport in full security lock-down. As I was boarding I passed a series ads from the HSBC's 'point of view' campaign, and one in particular struck me:

"Wouldn't the world be a dull place if everyone shared the same opinion?"

Considering recent events, both in the UK and the Middle East, that point seemed more debatable than usual (not to mention rather ironic).
It also occurred to me what a western presumption that was. In consensus or 'middle way' driven Asian cultures the societal ideal is that everyone shares the same view.
