I'm genuinely interested in how that perspective came to be since it is, to my world view, a shocking and hard to believe claim. But, my surprise isn't worth anything. I'm unable to find search term that gives something relevant, so anything would help.

But, I think it's a bit unfair to make, what appears to be, a very bold assertion, without explaining it or allowing criticism. I have no interest (or qualification) to criticize your sources, but I would hope that someone would criticize mine.
