#8 - Perhaps I should have said that I was referring to most people I've encountered (spoken to/read) in mainstream linguistics, but no doubt there are still many who do think it holds weight.

A comment on Language Log says this:
It's a much more controversial claim to say that different languages exclude certain types of thinking and expression than it is to say that a particular language imposes on relatedness in a cognitive map (precedence vs. possibility). The only reason to be uneasy on the 'anti' side is the potential for reenforcement of lazy arguments in support of more controversial claims, the conclusions of the study themselves are difficult to argue with.
The claim that "different languages exclude certain types of thinking and expression" is the strong form of Sapir-Whorf.
