It's actually so sad that the country has armed dangerous paranoid psychopaths. Everyone not pro-gun has to thread carefully to avoid being executed by some asshole in a truck.
Not everyone who owns a gun and knows how to use it is necessarily pro-gun. Some people have them because they are reacting to living in a gun ridden country. We can't get rid of them at the moment, so it's not a bad idea to learn how to protect yourself in the meantime.
That being said, even gun owners have to tread carefully around certain types of people.
