Frank. My children have not been brought up to be prejudiced, and neither was I. Quite the opposite. I was talking about their independent (yet identical) observations of a group of students they rubbed shoulders with, in two different establishments, having barely met or mixed with a Chinese person before, in their lives.
They also mix with students of many other nationalities and ethnicities, (especially now as we live in the Middle East where there are huge amounts of expats from all over the world, the minority are white, and there is barely a white/European child amongst any of their friends) and they do not appear to have made any 'blanket' observations about their behaviours that I am aware of.
We know very well, thank you, that whatever people's colour, religion, ethnicity or culture, they are all 'fully human' as you put it, with the full range of personalities, foibles and emotions.
The point is, I was not referring to Chinese people as one homogenous group. I was not referring to my opinion/impression of Chinese people as one homogenous group. I was referring to my children's observations/impressions of two very tiny, (and for all I know, quite possibly non-representative) groups, and it was in the context of a discussion about an emerging trend for Tiger Mothering, which seems to be not exclusively, but predominantly a Chinese thing. If those observations touched a raw nerve for you because they happened to concur with things you have heard before that make you feel defensive and uncomfortable then I don't really know what I can say about that. 
I'm quite sure they have wonderful personalities, but my children never get the chance to see them because they choose not to mix or to join social activities in the halls of residence/boarding houses, and they stay in their rooms studying pretty much all of the time.
All the while you wish to assume that that is somehow because of a fault, or a lack of effort, or a demonstration of ingrained xenophobia/predudice on the part of my children, I really don't see what I can say to convince you otherwise.
It is interesting that in defence of the Chinese students, Alliez made this comment:
'FNelson, please don't euphemise binge drinking to the extent of passing out in the street and having alcohol-related liver disease by age 25 as "partying"; practical jokes ending up in criminal damage and A&E as "larks" etc. And as for a culture that is able to produce uni students who instead of all this study -Britain should all learn from that culture.'
Now I don't disagree with any of that - she has a point, and it's a point I made myself, before I deleted my long post. It rings true (sadly) for too many British young people, and now I live somewhere where alcohol is not freely available and where public raucousness is not accepted, I can agree that we DO have a great deal to learn from other cultures. However, if I were wanting to get all huffy and offended about sweeping generalisations and 'negative stereotyping' of my culture, and wild derogatory assumptions being made about my children, and about how I was accused of 'euphemising' to gloss over the slack and anti-social behaviour they OBVIOUSLY must indulge in by dint of being British and white, then I could find a great deal to be offended by in what she said.
People (often, and in general) display common cultural traits. good, bad, indifferent and just plain bewildering, depending on which other culture is observing. It's a fact. Cultural traits are not ethnic traits. I'm not sure that ethnic traits actually exist, but obviously there will be some sort of unavoidable crossover between culture and ethnicity, and surely you are over-thinking things and developing a persecution complex if you cannot tell the difference between a discussion on common cultural traits and thinly veiled derogatory stereotyping of a whole ethnicity? Although I wonder sometimes....hence why I find these discussions wearisome and depressingly predictable, like walking through a minefield filled with booby-traps designed to expose me as a Bad Person for saying what I see.
The phrase trotted out regularly on MN: 'even a positive sterotype is still a stereotype'. Well, yes, but how the hell are you ever to explore the human race at all, and to learn from one another, if you are in such fear of recognising patterns in cultural behaviours, but dare not day it for fear saying the wrong thing? As a white British person I have to live with the fact that globally speaking, I am seen as fat, lazy, entitled, tattooed, promiscuous, a football thug or a Political bully and all-round Busybody. Or failing that, I am a horsey, chinless braying twit. I am none of those things actually (ok, I am a bit fat) and neither are the vast majority of the people I know, but there is not a damn thing I can do about it because IT IS WHAT THE REST OF THE WORLD SEES. So I must take it on the chin.
By the way, I am aware that in China it is common to refer to white Westerners as Big Noses. I'd like it on record that my nose is really rather small, with no discernable bridge. However, I do accept that as we probably all look the same to the Chinese, we are an ethnicity who in general terms are all in possession of Huge Hooters. I could go on a one-woman crusade to convince them otherwise, but while they look around and see many of us sporting massive beaky konks which to their eyes seem alien and unwieldy, then I must accept that they see what they see, and make their own conclusions - as they are perfectly entitled to do.
