Most excellent. Ferguson is clearly the most irritating of all US public intellectuals (that isnīt an evolutionary psychologist or Camille Paglia).
The fact that he is going to work with A.C. Grayling at that ridiculous "humanities school" further underlines this point.
Does teaching/working in America for a few years make him not British anymore?
Considering that he's pretty explicitly disowned the UK, I'd say US intellectual is pretty fair. Though what he really is is the last gasp of that early-mid 20th century creature, homo atlanticus.
Disowning Britain doesn't make him any less British.
