Your take isn't informed, as the reasoning behind the change, as explained by the editorial teams I linked above, and which has been debated academically, is an explicit counter to your primary argument.

You are misrepresenting my position. My comment was to the effect that they are real people and that you are trying to reduce and dismiss their ethnicities.
