Until your BFF Trump, who approaches every aspect of life as if it were merely transactional, a deal to be made, got the idea in his head that he "Needs" Greenland, whether or not Greenland "wants" or "needs" him or this country, with its failing health, housing, education, and other standards by which our fellow wealthy nations exceed us on all counts, no one ever heard Greenland say a word about wanting to be "bought" by Donald Trump.  
   That Trump turned a deaf ear to Greenland, as Greenland was strongly rebuffing his attention was an echo and sharp reminder of Trump's reputation and behavior as a "lady's man", as recorded on the infamous Hollywood Access tapes, when he bragged of simply approaching women and "grabbing them by the p___y"-- "When you're a celebrity they just let you do it".   That -- and of course, his being an adjudicated rapist (cf E Jeanne Carroll)

And even after Trump sent his special envoys:  Don Jr., (who may or may not have been coked up for the visit); MAGA vote-getter and teen cheerleader Charlie Kirk; and a random staff member; the trip did not find Greenlanders rolling out the welcome mat. 

Charlie Kirk's post above is a distortion of the truth ("Greenland wants independence from Denmark") 
Greenland attained home rule, including its own parliament, in 1979.  A series of other offical acts following that, concluded in 2009, with Greenland securing the right to claim independence through a vote.  At no time, including during this "tourist" visit, has Greenland ever made any signs of being for sale, nor has Denmark said anything to that effect either.
 
The following article in The New Republic sums up the general attitude in Greenland, as well as elsewhere outside of the less than sensitive circle of Trump & Son + associates:
