The exact date Leif reached Vinland is not known but it was in the fall. Wisconsin designated October 9 as Leif Erikson Day as far back as 1929 and Congress later named October 9 as Leif Erikson Day for the nation. I don't know if it was proclaimed this year.
Leif doesn't furnish as good a target as Christopher Columbus--he didn't try to enslave any of the natives and he isn't known to have brought any European diseases along.
Leif Erikson was certainly a slave owner and had violent confrontations with Indians. It would have been unusual for a Viking not to capture slaves. There’s just much less of a written record than with Columbus.
And, in the end, Leif Erikson probably became a Christian, sealing his fate as white supremacist.
The Vikings in Canada present no target at all because they lost to the Indians; I believe they referred to them as “skraelings”. There seemed to be an infinite supply of them, and the settlements were abandoned.
