Why do haplogroups matter?

[Arhat]

Indo-Europeanness was/is more than just haplogroups and he knows it. His maternal grandfather or more distant ancestors might as well have had R1b or R1a.

Also his I1 haplogroup was spread by Indo-Europeans and only became with them so frequent even if it is originally of pre-IE origin. It probably was brought to Scandinavia by Indo-Europeans from Central Europe which absorbed it from Funnel Beakers or Globular Amphora.

Of course; but he copes by claiming his I1 as Indo European; that's a separate argument to an autosomal one. Obviously most of his other paternal lines are probably R1b.

Just like the early Slavs had I2-din besides R1a.
