Though dated, McWilliams' work here challenges the assumptions of the the "white" majority in the US even today (I found and read Brothers Under the Skin in 2008). While there are many works on this issue today, This book reminds me of another book I read in the 60's "Black Like Me," that was the first real "eye opener" for me as a young white male in the US culture as to the reality and evilness of racism. Brothers Under the Skin takes on the topic at a broader level demonstrating the way "white" non-white categories targets and affects a broad spectrum of people. Both of these older books drive home how embedded racism is in our culture and in us as members of this culture even today over 40 years since their publication. ( )
