Mad or Gonzo?

From the Guardian’s leader “Hunter S. Thompson: A libertarian legacy”, acknowledging the suicide of the "gonzo journalist":

“Thompson shot from the hip both literally and metaphorically and he was often portrayed as a drug-crazed eccentric. His warning signs on the road to his home of ‘guns in constant use’ and his furious rants in print and in interviews led to him being labelled by his enemies and detractors as ‘mad.’ But there was at the heart of his journalism a visceral hatred of bullies and crooks and hypocrites, the very people he felt had taken over the government of his beloved country. In his Devil's Dictionary, Ambrose Bierce, who could perhaps be seen as the grandfather of ‘gonzo’ journalism, defined ‘mad’ as ‘affected with a high degree of intellectual independence’.”
