I have found a list of strange phobias on the Internet: The Phobia List.
A phobia is not something to ridicule. But even people who suffer from Genuphobia (fear of knees) or Aulophobia (fear of flutes) should probably be able to see the fun in the disorder?
Or maybe not, if they suffer from Geliophobia (fear of laughing) or Catagelophobia (fear of being ridiculed).
I can not decide if the most bizarre are the things that people fear – or that someone has invented names for these disorders.
One of the most ironic phobia names must surely be Hippopotomonstrosesquipedaliophobia which means fear of long words. That could almost lead to Phobophobia (fear of phobias).
