Americans are afraid to go to Europe because of terror attacks. Europeans are afraid to come to the US because of tornadoes, earthquakes and guns.
Wow, we must all live in really scary places if we're afraid to visit each other!
I think I speak for most Americans when I say that I've never been personally affected by gun violence, tornadoes, or earthquakes. I grew up wandering New York City as a teen in the '80s, I student-taught high school in the South Bronx, and have extensive family living in the Midwest tornado zones. Would I *ever even think that it is too dangerous for someone to come to the US for a visit?? Do you think I would be raising my children here if I thought it was that dangerous?
I have a feeling that Europeans feel the same way: some terrible events have happened, but 99.99% of life goes on just the way it does in the United States.
You're at more risk in your shower and on your drive to work. Don't let fear-mongering news reports obscure the statistical facts. When we use bad math to restrict our lives, the terrorists win and we and our families become ever more insular, provincial, and afraid.
