... of stuff? Any kind of stuff. You don't even have to say what. Just vote yes or no, and whether you say what it is or not is up to you. Of course, the best way to overcome a fear is to face it.
You might try this: There's an old Japanese legend that says if you write what you're afraid of on your hand and make like you're eating it, it'll be easier to overcome. I haven't tried it myself, but still.
Personally, I have a fear of deep waters. I don't know what's down there, but I know the majority is out to get me, and I can't swim, so... yeah. I guess it's a good thing I live in a landlocked state.
Now that I've said my uber-embarrassing fear, get to voting.
