Hm IMO one of the most liberal thinkers in Denmark in early 18th century was Ludvig Holberg (Norwegian) Pretty sure he got more out of visiting places south of Denmark than attending the University of Copenhagen.
It took Struensee (German) to do all kinds of reforms later on, but that cost him his head as he was doing too much too fast, and knocking up the queen did not help either.
So I would not call Denmark a place with many liberal thinkers until much later.
