A lot of Americans need guns to feel safe because:
1. Fox News, Rush Limbaugh, Alex Jones, apocalypse/doomsday preppers, put fear into people's brains. When you are afraid, the higher, thinking parts of your brain lose blood supply to the lower, fear-based areas. The fight or flight response of these areas cause people to ignore cognitive dissonance and they end up being nearly hypnotized by what they see and hear from these fear mongers. The fear-based media makes a lot of advertising dollars when these people watch or listen to them! So does the NRA!!
2. Some people are very insecure and need a weapon to make them feel more powerful. Many are men who have small hands.
