What is wrong with people from the USA?

I am German, and currently in Thailand for the last 9 months or so. I have been to other countries (Ireland for example), but it is getting frustrating to see how bad the reputation of the USA is. I have met hundreds of people from all over the world (including the USA) and otherwise, Americans are usually super friendly and nice. But I made some observations about American tourists, and I honestly don't get it.<br><br>1. Why do most Americans not speak any other language than English? I get it if you don't speak Thai, nobody here does. But why do you go to another country if you can't even speak a global language like French, German or Spanish? I have met Americans who couldn't even count to three in another language. It is honestly kind of rude if you go to another country and expect everybody to speak English.<br><br>2. I live in Chiang Mai, where it is relatively cold for Thai standards. Still around 25-30°C during the day, and even warmer during the rain. Why do I see Americans walking around in winter clothes? It is 10.000.000° outside. I have seen Americans walking around with snow shoes. Why on earth would you do that? It is not cold here!!!<br><br>3. Americans are usually super loud and rude. I have gotten used to it by now. They usually talk to the locals like they were dumb or something. I have even seen Americans shouting at locals because they couldn't answer a question. I get it if Americans can't speak Thai, but locals usually speak enough English to communicate. So why shout at them?<br><br>4. Why do Americans drink so much? I am not a drinker, but I have seen Americans drink until they pass out. I have even seen Americans being carried by locals because they were too drunk to walk. By the way, isn't drinking under 21 years old illegal in the US? I have seen Americans who couldn't be older than 18 drink until they passed out.<br><br>5. I have never seen so many overweight people in my life. I thought it was just a stereotype, but it is sadly true. I go to a local market every day to buy food, and I usually see 3-4 Americans there a day. Most of them can barely walk. I have even seen Americans calling taxis for a 2km distance because they couldn't walk it. I have even seen Americans ask about escalators at the airport, because they couldn't walk up a single flight of stairs.<br><br>6. Why do Americans give locals a hard time about tips? I have seen Americans shout at locals because they didn't get their change back fast enough. I have even seen Americans give locals a hard time because they gave them a 10% tip and not a 20% tip. Why on earth do you expect tips in a foreign country? Tips are even more expected in the USA than in Germany. Why do you complain when locals don't give you tips?<br><br>7. Why do Americans think they are superior to other countries? I have heard Americans say that "If you don't speak English, you are an idiot". I have even heard Americans say that "If you don't speak English, you should kill yourself". honestly? What the hell is wrong with you? Why do Americans think they are better than other countries? I have lived in the USA before, and I liked my time there. But the people were honestly not great. I was called a Nazi because I am German, and I was called a terrorist because I am Muslim. Even if I wasn't Muslim, I wouldn't think it is okay to call somebody a terrorist because of their religion.<br><br>I know that not all Americans are like that. I have met many friendly Americans who were very nice. I have lived in the USA for 3 months, and I liked most of the people I met. But I have honestly never seen so many rude people in my life. In my home country, everybody is usually super friendly, and I never experienced something like that. I have lived in Ireland for a year, and I didn't experience anything like that either. Honestly, what is wrong with you guys?
