Please do not make us a monolith. I am not my country, I was just born here. That kind of thinking leads to radicalism and violence. I can perfectly understand caution with “unknowns” from a group you have reason to be concerned about. Honestly from a personal safety standpoint we do this all the time. But to unilaterally decide we are all one thing and write us off (or worse) is false and dangerous.
I don’t know where you are in Europe but I love the continent and have visited many countries there. I do my best to be respectful when I visit and look up local cultures and norms so I don’t stand out and be “that American.” I’m not ashamed of being an American tourist, but I don’t want to adhere to the worst of our stereotypes. If other countries’ people decide we are inherently dangerous, being annoying may be the least of my worries should I have the fortune of making another trip there.
My sister and I are in Columbus for a concert and we were in a store right across the street from this happening. Shook us up pretty good. I have never seen something like that before.
