I Find That Offensive! by Claire Fox

When you hear that now ubiquitous phrase "I find that offensive," you know you're being told to shut up. Social discourse is now dominated by competitive offence-claiming. But how did we become so thin-skinned? This book blames three culprits: official multiculturalism's relativistic conflation of tolerance with positive "recognition," narcissistic identity politics, and finally therapeutic educational interventions such as anti-bullying campaigns.

Claire Fox is a British libertarian writer. She is the founder of the Institute of Ideas think tank and a broadcaster and social commentator, appearing regularly on BBC television and radio.
