Another example:
Shakespeare’s The Merchant of Venice (1605) is certainly anti-Semitic from a contemporary perspective, but it was probably considerably less anti-Semitic than was usual within mainstream English culture at the time. On the other hand, Ezra Pound is a more recent and more troublingly anti-Semitic writer, who—to make matters worse—was writing in the lead-up to and during the Holocaust. Although Foster himself (along with many readers) still engages with Pound’s work, it is understandable that others choose not to.
