I can certainly agree with some of those similarities but most of them I would attribute to the weather combined with a generally working class culture (at least in the North of England, not sure about Scandinavia). As I understand it, prizing roast meats goes back to its rare availability to working class people from the industrial era (where Yorkshire at least derives much of its modern culture). Beer is common to working class areas and whiskey to cold areas. Woollen clothes help with the cold. Social egalitarianism is more of a working class thing.

Not to say there aren't links, there certainly are, but I wouldn't say they are strongly culturally bound compared to our relationship with Western Europe.
