> as an American [...] I don't know if others share that same worldview.

I'm far from American, but have the same "blood", but I think it has nothing to do with being American/Swedish/Spanish/whatever, some people have different personalities, upbringings and strengths/weaknesses simply.

Americans aren't "tougher-skinned" by default or anything, at least I didn't get that experience from interacting with Americans.
