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.

Certainly the Vikings captured slaves--plenty of evidence for that. The modern-day Icelanders have Celtic DNA inherited from slave women brought by the Norse colonizers of the island. But whether Leif personally owned any slaves, I don't know.

He definitely was a Christian--had become one shortly before his exploration of the lands to the west of Greenland (seen earlier in 986 by Bjarni Herjolfsson, who had not gone ashore). He converted his mother but not his father to Christianity.
