Sorry I didn't know you were an Evolutionary Scientist, guess that makes you the valid one, right?
Then I can't say because because I haven't read those mentioned books, but I won't be taking your words for it either.
But hey even Jordan Peterson said ridiculous things every now and then. No one's perfect.
Edit: BTW, I looked up if he wrote a book called, "Ethnocentricity", he hasn't. I guess you're not so valid after all.
