I’ve been amazed by the response to my decision to leave my band, Mumford & Sons. The article in which I explained why has now been read 700,000 times and has been republished by newspapers in the UK, the US and Germany. My main hope in publishing it was to restore my own sense of integrity — eroded, I felt, by an apology I made to an extreme but vociferous internet minority who took great exception to what I considered an innocuous tweet to Andy Ngo, the author of a bestselling book about the radicalised far-left. Just as I never anticipated the angry reaction to my unremarkable tweet, I could never have foreseen that my article about the ensuing fuss would have generated so many messages of gratitude. Gratitude for what? Not for leaving the band — although a few people may be glad.
