An interesting list and I picked out those I found THE most interesting to me... Funny that there are 4 or 5 words that designate Fear of Cats but only one for Fear of Snakes! Several definitions are like that with the "One Offs" being the more interesting to me...
We all fear something. No one is 100% fearless. I, myself, fear someone hurting others and even up til a certain age, I feared clowns...
My biggest fear is Demophobia, fear of crowds. I do not adjust well in front of strangers and at times I have to go inside myself deep to layer a certain sense of removal from strangers and crowds.. It is lumped under Social Anxiety by the Psychiatrists and it is... Yet, once I get to know you, good luck getting me to shut up!
Enjoy.
Though it does not say, I do not believe this list is all-inclusive.

My greatest fear is of being ignorant.

That's a long list. I used to have a fear of walking past people on a sidewalk. I remember I could hardly breathe and it felt like I was walking through really thick air that was holding me back. Thankfully I got over it. I've got new fears now.

I'm with Balth, but phobia's are hard for other's to understand because they are irrational. The good news is that there is very good treatment for phobia's
