In most places in EU it is quote normal to go for a walk alone at night, or do whatever you like whenever you like and you feel rather safe doing it (amongst many other things).
Also you can look people in the eyes and no one is going to attack you for it.
No one follows you in stores and watches if you'll steal something.
Rarely (or ever in my case) anyone ever approaches you in an insanely inappropriate way.
All of these are the opposite in the US it seems.
Are you aware people do not see the US as a beautiful utopia but rather the opposite?
*I won't touch on the guns issue, that is self-evident.
