In U.S. each state has its laws. One reason is because not all Americans have the same attitude, behavior or belief. In her book “Ten Interesting Things About Human Behavior“, Suzanne L. Davis explains how you can change your attitude by changing your behavior:
Here is how it works. I used to live in Chicago, where it was illegal to carry a concealed weapon. Nobody I knew owned a gun, and most thought that guns equaled crime and the fewer guns in the streets, the better. When I moved to Houston, I learned that most Texans had very different feelings toward guns, associating them with personal safety, defense of the home, sport (e.g., target practice, hunting). The first time I visited my next-door neighbors, I was introduced to their gun collection, which was displayed in a quite impressive gun cabinet.
I was puzzled. I couldn’t reconcile the fact that my neighbors and many other good upstanding citizens owned and enjoyed guns. I was in conflict over what I came to Houston believing (guns equal crime) and how I was behaving (interacting with nice gun owners). Over time, I became more comfortable with the idea of citizens being able to carry guns. My attitude about guns changed to be consistent with my behavior.
This is a wonderful example about how we can change our attitude about something once we change our behavior. My attitude about Americans changed when I came to the U.S. and meet with many nice people. Some Americans I meet told me how their attitudes about Arabs changed when they visited the Arab world.
Isn’t hypocritical of us to feel normal to pick our nose but we feel disgusted when we see someone else do it. I know it is an ‘Ewww’ thing to write but don’t say you have never picked your nose.
