Something dangerous is brewing beneath the surface in our country, and it worries me that warning lights are not flashing in the minds of many of those I respect most. After the discrediting of anti-Semitism, after the discrediting of discrimination against black people, after the discrediting of prejudice towards the Irish, I hadn’t expected to live to see a powerful generalised antipathy against any race or religion gather popular force here without stirring at least the more liberal of my fellow citizens into resistance.
