"I find it telling that there are UK contributors here, whose only idea of what constitutes "multi-cultural" to mean the dominant European cultures" - I've just read through the thread again, and I honestly can't identify who are being referred to here, and what they said to deserve that.

Of course, except when words like honour and labour andtheatre and so on come up, it's a bit hard to tell the UK from the US sometimes (and even then the "English" spellings might just as well be Irish or Australian, or indeeds most part of the English speaking world outside the USA). But I've tried to see how the contributions which look like they are probably UK (in this broader idiosyncratic use of the term) can be interpreted in this way, and I couldn't do it.

I really don't think there's too much disagreement here.
