Different meaning to 'reality'.

ie., social-historical vs. material-historical.

Since black vikings are not part of material history, the model is not reflecting reality.

Calling social-historical ideas 'reality' is the problem with the parent comment. They arent, and it lets the riggers at google off the hook. Colorising people of history isnt a reality corrective, it's merely anti-social-history, not pro-material-reality

I agree with you, and I think you have misunderstood the nuance of the parent comment. He is not letting google "off the hook", but rather being tongue-in-cheek/slightly satirical when he says that the reality is too troubling for google. Which I believe is exactly what you mean when you call it "anti-social-history, not pro-material-reality ".
