I think your perspective and critique is valid and interesting but it can be helpful to assume the best in people, especially when giving a critique.
In my experience, kids (and adults) love the fact that Iceland is greener and Greenland is icier, so it’s not surprising to me that other languages have similar odd names. It’s not surprising to me that some people would have a biased opinion of a place due to an odd name, but like Iceland I expect many know much more about a country than just the name and thus the name doesn’t hold much weight.
