Fear of clowns
Here's a link to an NPR story I listened to on the way home (sorry, the sound won't be linked until 7pm EST, about, oh 10 minutes from now)
In Britain, fear of clowns is #3 on the list of phobias, right behind needles, and spiders (not afraid of needles, and am rationally cautious around spiders, in case they are the kind with a poisen bite. Otherwise, live and let live, I say).
I can't say I'm Afraid of clowns, but I certainly don't like them.
Thinking about why, it's mostly that they are wearing a disguise, and you can't see Them, who they really are.
What are they hiding? Why does anyone have to distort their features so much that the person underneath can't be recognized?
Those blue people from Avatar? You could see who were though. Same with people who wear their hair spiked, are tatooed (well most people), who color their hair, or wear edgy clothes.
They are showing who they are, and you can see their expressions.
A clown, IMHO really doesn't look like a person at all.
It could be an evil alien, or the clown from IT, or John Wayne Gacey.
hmmm...a lot of it also has to do with the idea when you see one, you're supposed to feel they are funny, you're sorta obligated to notice them, their antics, and laugh.
I don't even like looking them in the eye, they are deceptive. In any case, I think they look more evil than good.
