1. I don't fear death, it will come to all of us eventually.
2. I don't fear global warming, natural cycles are inevitable. We can and will adjust.
3. Crime? I will protect myself and my people. If that fails, see #1
4. Immigration? If my job gets taken, then I will find something else to do.
The government run amuck is my only concern, and I wouldn't even call that a fear.... they can and could make life very difficult for every last person in this country.
Spiders and snakes, on the other hand........
