Yes. I have a PhD in immunology - I'm not a medical doctor, though I do teach second year medical students. If a family member gets sick (especially the children), I get called. If a family doctor suggests a treatment, I get called for a second opinion. Swine flu outbreak? I was receiving dozens of emails a day from concerned family members. So while we (and I use 'we' very loosely as I'm not an MD) aren't asked to 'perform surgery', we are asked to provide free medical services.
The ethics problem is represented by an experience I had while at an American research university. A Chinese faculty member met with the Chinese students in order to tell them in America, cheating and other ethical breaches are not considered a good way to get ahead. This suggested certain cultural differences which should not be used to discriminate, but need to be recognized because of the risks involved.
While I certaily wasn't at that talk (and I suspect that neither were you), I'm willing to bet that you don't completely understand what the talk was about. I'm on the faculty of a top tier reserch insitution conducting immunological research - I've had several Chinese graduate students, have sat on the international admissions committee, and have given the talk that you describe to our new Chinese students. The problem isn't one of ethics, but one of culture. The Chinese don't regard plagiarism the same way we do - in fact, the educational system encourages it in a way as it is an honor, of sorts, to 'plagiarize' your mentor. Additionally, a lot of these students don't have confidence in their english, so whey they write they occassionally take an idea from another article and copy it verbatim thinking "that's exactly what I was thinking, and I don't have to worry about incorrect english" - in most cases, there is not an intention of deceit. The Chinese certainly have their issues (admitting mistakes and nationalism), but I wouldn't call them unethical.

The protection has less to do with absorption reduction than a distribution of force.
I'm sure Grace Wang would agree with you.
In brief, Grace Wang was an international student at Duke and dared to try an initiate a discussion between the pro-Tibet and pro-Chinese sides of a protest. After being attacked on forums such as mitbbs.com "Online Vigilantes" decided to bring these attacks to the real world by posting her personal information (her student visa application) and providing maps to her parents' house (which was defaced, causing her parents to go into hiding).
Defending kittens are one thing, but as with "think of the children", it rarely stops there.
