The many "you're wrong if you believe that" made me remember the anecdote of Alan Kay attending some conference about OOP and saying that it was wrong, that he invented OOP and it was not like that.
IIRC, Kay's vision is that OOP is about messages.
I have my own pet theory, of course it must be wrong too, but if I may, only as food for thought: The core usefulness of OOP is usability. A language is a matter of connecting thoughts through a mental model. Subject, verb, predicate. Object, method, parameters. That's mostly it. The rest are implementation details and lots of bikeshedding.
