For the person scared of guns, I'd be more than happy to arrange a safe, controlled experience for you, if you were ever in the states. Firearms are very fascinating tools, and very fun, once you learn how to handle them safely.
Bugs do not scare me(quite the opposite). I have pet bugs. Many species of Cockroach are just amazingly colorful and beautiful.
Worms freak me the hell out, though.
I wouldn't say I'm afraid of Democrats
per se, but we shall see soon.
Riding still scares me a bit.
Large crowds of people. (I'm working on this one.)
Dark plausible scenarios of "what ifs".
