On the Claim by Those On the Alt-Right that Jordan Peterson's Question, "What Is White?" Is a Ludicrous One

Well, being that a) there are just four recognized races (some biologists think that there is enough genetic differentiation between American Indians and East Asians for the latter to be a separate race but there isn't a consensus at this juncture) and b) Arabs/North Africans and South Asians (people from Pakistan, India, Sri Lanka, etc.) are generally considered to be a part of the Caucasian race, I really can't say that Professor Peterson's query is all that out of bounds (though, yes, I do agree with the alt-right that multiculturalism has been an absolute failure and that third-world immigration probably needs to be monitored at this point). My opinion, at least.
