Actually, you're not completely off base here...the Danish Vikings who cruised the British Isles were the warlike, rapacious lot; but, the Swedish Vikings traveling south into Europe were more likely to trade with you as kill you.
Our tour guide and bus driver on my tour of Ireland 5 years ago would regale the passengers every time we came to a near collision with our huge bus on the impossibly narrow Irish roads.
"Viking!" he would spat while he muttered a disgusted oath under his breath at the driver of every oncoming car that cut too close to our bus.
Thanx 4 those kind words re Swedes....
