Afairyist

But consider this: your typical atheist does not believe in fairies, goblins, sprites, water nymphs, demons, angels, ghosts or elves either. Why not call him an 'afairyist', or an 'agoblinist', or an 'anymphist', and so endlessly on?

Nobody can actually say for certain that anything doesn't exist, but I'm an atheist in the same way as I am an aleprechaunist and an afairyist and an apinkunicornist.
