I don't think "European children will look at the map and feel less significant" is a carefully neutral observation. It's an assumption that European children feel superiority because their country is slightly bigger.

If anything, I expect the accurate sizes set the stage for feeling superiority over their ancestors colonizing huge lands while coming from tiny countries.

If we're talking about kids, they should just get taught this type of geography using a globe. You can get an accurate (enough) inflatable globe for like 3 euros, including shipping.

Because it’s focusing purely on how big continents “look” without even mentioning the issue of actual size. That is not, in any credible sense, “carefully neutral”.
