As far as I know, there are several ways worldwide to interpret the world we live in.
Usaians and canadians interpret the continents as 7 worldwide (North America, South America, Europe, Africa, Asia, Oceania and Antarctica) but there are countries in Europe that consider America as a whole, making a total of 6 continents, there are even countries that say that Antarctica isn't a continent but just an icemass. Any interpretation of the continents I mentioned are completely valid in the United Nations, so Greenland is part of America as it is part of North America, so none of you are wrong, but it is wrong to correct other cultures in that matter, since the education system are different but both valid.
