Alt. Hist. request, Vikings make a go of the "New World"?

Vikings were in America?
How did they get on with the indigenous folk?

There is a popular perception that the Vikings are adventurous, wily and adaptable.  But I think in the one case where they got out of the comfort zone of familiar European and near east civilization and had prolonged contact with indigenous people, they proved anything but. This is seem in the 300 year coexistence between the Viking and the Inuit in Greenland.  

The Vikings called the first Inuits they encountered  “skrealing”, meaning wretch, and stabbed them with swords just to see if these wretch’s would bleed.  Over the next 300 years, the Vikings on Greenland rigidly followed the pastoral way of life familiar from Ireland and Scandinavia, despite its unsuitability to conditions in Greenland as the little ice age set in.  They imported luxury goods from Europe to keep up apparences, and despite struggling just to survive, build large cathedrals.  They totally ignored the fact that they could see the Inuits were well adopted to the cooling condition and were doing just fine, even though archeological evidence shows the Vikings were having harder and harder times raising cattle in grenland’s Unsuitable climate.   In the adopted nothing from Inuit technology or way of life for 300 years.  As a result the Greenland Vikings eventually died out completely in Greenland.

Based on this, one may suspect Viking’s outlook in America is clouded by their own bad cultural attitudes.
