If I had one minor superpower...
...it would be to be able to cast a spell over the world so that no one would ever react to people like Katie Hopkins, Piers Morgan et al, thus starving them of the oxygen of attention, reaction and publicity. The pleasure I would derive from watching them wither and die as no one takes a blind bit of notice to their increasingly desperate provocation would be akin to witnessing the last seconds of Donald's Trump US presidency.
