Jo, I wish I believed it was as you say - that's such an optimistic way of looking at things.
Having lived in the UK, Japan, Australia, Chicago and Toronto (and now Australia again) I'm not so optimistic. While the fuss about words may be different, there's a lot of overlap in the attitudes.
You could equally well argue (not that I am doing!) that Europe / Australia haven't gone down the PC route because so many people are unconcerned by the use of potentially offensive language.
I did read something once saying that a different ethnic population tended to be tolerated until it reached 15% or more of the total population. At that ratio it could be perceived as a threat and hence discrimination began. This might explain why in the US the strongest racism is against the blacks, in Australia against the Asians (and the Aborigines, but I'm in Sydney, there are far more Asians than Aborigines here and that's the racism I hear more!) and in the UK against the Indian subcontinent races (Pakkis.)
At least, it seems to fit my experience.
