This book started as an affirmative answer to the late Susan Moller Okin's question: is multiculturalism bad for women? Over time, however, the suspicion grew that multiculturalism is not only bad for minority ethnic women, but for their male counterparts, young people, and, indeed, for minority ethnic and religious communities as a whole. Once research showed that this suspicion is supported by empirical evidence, it is clear that multiculturalism is actually bad for majorities as well as minorities; indeed, for liberal democracy, and thus for British society as a whole. This suspicion is also confirmed by empirical evidence, particularly in the arenas of academia, policy-making and professional practice, where the dominance of multiculturalism as a political ideology has had profoundly negative consequences. This controversial book analyses these arenas, including the suppression of research findings, the law-making process, and the paralysing of professional practice.
