I make a habit of reading books and articles that I expect to find disagreeable. This serves to test my convictions as I bounce them off opposing views and discover whether or not they survive the collisions. Moreover, the willingness to seek out alternate views invariably teaches you something that you did not know. In fact, sometimes you actually learn that your understanding of the issue was completely wrong altogether.
The fact that Robin DiAngelo’s ‘White Fragility’ did not manage to be informative or useful on any level is an achievement in and of itself. I’ve never encountered a book so intellectually vapid as to make me worry that reading it may have actually subtracted some knowledge.
