Using the APA's criteria for antisocial personality disorder to 'diagnose' ELT as suffering from a medical condition is, in my view, a very effective framework for presenting Gerald's thesis. It allows Gerald to turn the tables on ELT, by presenting something that is usually regarded as healthy and innocuous as being, in fact, seriously unwell and very destructive [.] there is still relatively little published literature that is concerned with the concept of whiteness in ELT, which makes this an important book in terms of its contribution to the wider discourse problematizing deeply embedded structures and ideologies [.] the author's account of his own course, 'Decentering and Decoding Whiteness', provides a useful template that teacher educators can follow to bring anti-whiteness education into their own practice. The syllabus and overall approach are very informative, and could perhaps be adapted and used in a wider range of contexts.
