It's politically unacceptable to say so, but some human cultures are clearly worse than others, and yes, I expect there probably is a best culture. I wouldn't begin to guess at which one that is, but I would take people seriously if they're saying that a particular culture has got particular things right and other cultures can learn from that. The problem with imperialism was less the culture and more the exploitation and theft, which is not really relevant to the programming language case.
