Skarpi, if you study Irish history far enough you will find the Danish connection.
They raided towns and villages carrying away slaves and loot, leaving survivors to starve.
They destroyed centres of culture and learning, the monastries.
Later they seized land and settled it themselves.
They did the same here.
But that is history. No one will go with guns and bombs to Denmark or Iceland to take revenge for what happened hundreds of years ago.
That would be stupid.
