Even intuitively, it would make sense that different languages/cultures might distinguish or understand different concepts differently...since this is HN, imagine asking a trial of 100 people who have programmed in nothing but COBOL their whole life to explain monads or continuations intuitively, and how they'd use them in practice, compared to a trial of 100 who understood Scheme and Haskell. I think the results would be pretty obvious. Why would structures and concepts in human language be any different?
I really don't understand the political posturing behind denying linguistic relativism (not that you're necessarily doing that, of course).
