I thought the exact same thing. I really like Walter Williams beliefs, but I think Thomas Sowell and Larry Elder are better writers.
My only concern is the idea that: "She is (name a race), she'll like (name an writer of that same race.)"
I love Elder, Williams, Sowell not because they are black, but because of their intelligence, passion and clarity.
So do I. I mentioned their names in the context of her not being alone. She had her own short list of role models as well.
