...it's difficult to explain, that's why it took me forever to answer. It's also all very sparse personal observations and it's highly possible they're all wrong.
The first thing that stuck out to me was, you're all very self-referential, to the point that you seem to forget that the rest of the world exists, at times. Granted, everybody has their own in-jokes, but you expect everybody to know what you're talking about and it's kind of confusing at times. Doubly so for political discussions because your political categories are unlike anything else I've met.
You are very...evangelical. If an European meets somebody they disagree with, they go "meh, what a dick" and move on. Americans instead want to convert that person. This is especially obvious in religious and political discourse. Europeans rarely talk about religion, and rarely the conversation gets heated. It's considered a highly personal thing and proselitying to random people, whatever your idea, is frowned up. Americans instead seem always ready to start a flame war.
You also are much more emotional than what I thought you would be. You speak with an open heart, you overshare, you get angry at the drop of a hat (I do that a lot too, but I'm an outlier where I am), you tend to answer to rational argument (I'm against Law X because Y) with emotional ones (I'm pro Law X because IT WILL AFFECT ME PERSONALLY AND ITS RESULT WOULD MAKE ME UNHAPPY DO YOU WANT TO MAKE ME UNHAPPY DO YOU DO YOU) (I AM NOT SAYING YOU ARE STUPID OR INCAPABLE OF THINKING RATIONALLY. It's just something I've noticed you do a lot).
I realized those are all sorta kinda not entirely positive, which is stupid because I find most of the weirdness nice actually. Like, Americans are enthusiast. Europeans lost the ability to feel enthusiasm at some point in '900, Americans never did. You really feel like you can do things! If you go out there! You can change the world! You really can! Europeans...let's just say we don't. This is like something that always sticks out ot me too, and it's very uplifting.
There's more stuff, but it's very late where I live.
