Hi Hoa,
You are pretty brave to dare this thread!
The discussion about the “as such” usage, to me, was actually more of a reflection of how we interpret what a noun or noun phrase is, rather than grammatical correctness. As I found on one of the site, it said:
"As such" -as being what is indicated or suggested. All I was doing was to confirm my interpreation and if there were others seeing it the same way. I am not saying right or wrong.
There is always this hidden bias that natives can communicate and write better than non-natives and therefore, in a debate situation, the non-native’s answer is likely deemed incorrect. Generally, it may be true. However, the reality is, even natives can’t seem to have a uniform answer or opinions to the same question in our everyday life sometimes. Not because they are wrong, it’s just because their answer is subject to personal interpretations and how they acquired their language skills. Mike Tyson is a famous, or infamous American native, would anyone care to comment on his English correctness or perhaps like to learn English from him? For the longest time, I had always thought “amongst” is a wrong word for “among” until I listen to Dr. Michael Savage's radio talk show who has two Ph.D’s. The man’s fluidity and command of the language is absolutely magical, aside from his personal view on issues. But one has to admire his wit and quickness on the language. I don’t want to offend any natives here by what I said. Please do take this in the negative light. If I do, I sincerely apologize.
