I am a northerner, but the north is associated with south. I have had people assume I go "yee haw!" even though I am not even from the south. A joke we have going on here is that we have grocery cart vehicles for people that are too fat to walk. It's true, we do have them 😂. I heard you are allowed to book a second seat on a plane if you are too large. While the food here can be high-fat and high sugar, believe it or not, not all Americans eat that sugary crap 24/7! I have also seen very fat people wear maternity clothes. And no, not all of us are racist and ignorant. There are racists no matter where you go, I welcome foreigners. And not every American is overly patriotic.
Part of why I myself am not patriotic about my country is because my parents are foreigners. I am the first of my family line of foreigners to be born in America. I have only celebrated American holidays a few times. While I am not the sharpest tool in the shed, I can vouch for the fact that not every American is stupid and lazy. No, I am not so fat I can't get through the door.
Not all Americans come from privileged backgrounds, I sure as hell didn't. I try to brush off the rude comments I have gotten as an American while laughing it off. I don't take these jokes seriously, in fact, I love jokes about America and stereotypical Americans! See? Not every American is incredibly sensitive.
