That's the weird (or is it common?) thing - I'm not afraid that they will hurt me or bite me - I realize that they are mostly harmless (at least where I live.).
I just find them... repulsive. I don't know how to put it differently, I just think they're ugly and unpleasant.
That's not weird. Very many people are repulsed by bugs for the same reason - bugs are just horrid.
But, if you wanted to work on it you'd be able to get to point where you wouldn't freak out every time you saw a bug and it would only take a few weeks. There's probably something online to help guide you through it.
