No - The debate has been exaggerated a bit, but the old-school ethnologists who wanted to defend that the peoples that they were studying were the One True Tribe were really very old school. There have been people who are hesitant to ignore the original interpretations, but there have been few if any anthropologists in the last 70 years that would deny that conquest and population movements were a major cultural factor in most areas of the world.

Edit: P.S., Tu quoque and argumentum ad hominem are both fallacies. Trying to suggest that my argument 'that people should look at the evidence' is wrong by pointing to people like me who have not looked at the evidence is hardly LessWrong worthy behavior.
