Iran has been by far the most friendly and welcoming people. And I visited -a lot- of places.

Also USA had very welcoming people, I must have been lucky by judging from people online, but in real world, my experience has always been very positive.

China. The people are super nice, sweet, helpful, lovely people. It's just their government I hate. I don't know if they hate it too or not since they're not free to say but I think they're nice people and they deserve better.

I’m wasn’t surprised but Mexico.

I was in the waiting room at a dentists office in Ciudad Obregón. Every single person that came in was greeted with a warm hello by every single person in the waiting room.

Netherlands. People there actually smile, it's crazy

And honestly the US. When I moved to Vancouver Island I started spending a lot of time on the Olympic peninsula and people in that region are ridiculously friendly. Port Angeles is like twice as friendly as Victoria it feels like

Turkey! I had such a wonderful visit there as a teen in no small part because of the locals we met.

Paris. I've always heard bad things about Parisians but they were cool. The only rude people I encountered were tourists.

I went to rome once, and I found people to be super unfriendly. Like, giving me looks levels of unfriendly.

After a few hours of this I realized the problem, I was wearing a Deicide t-shirt, and rome is christian as fuck. God I'm stupid.

After a quick change people were really nice :D

Cambodia. Genuinely the nicest, and most helpful, people I have ever encountered all throughout the country. I was told about their general friendliness before, but was blown away by actually seeing it firsthand.

Germany. Namely Northern Bavaria. They love it when you try to speak their language and suddenly you are their friend, they are speaking English to you, and they are buying you beer. Suffice it to say that I made a lot of friends there. An amazing experience.

New Zealand. So wanted to stay there. Made Canadians look a little rude. LOL.

France.

Was there on business, visiting a factory of a large vehicle manufacturer, down in the south east. My god these people were nice. There was a guy who made sure we had everything we needed to get our work done, who would literally jump and run if we needed anything. There were people bringing us mini choco croissants for meetings. They always invited us for lunch and paid for it. There was always coffee for us if we needed it. We had desks to work on, which is a rarity in a factory environment, but they made it possible.

The best part was when we were standing at the line with a special piece of equipment that we had brought, and a guy stopped and said "hey, that looks interesting, what's it for?" - and then we chatted about that for five minutes, eventually realizing it was time for a meeting. For both of us. Five minutes later, it turns out the guy who casually talked to us tech people was actually the head of their corporate IT. You wouldn't have been able to tell that he was some higher up because he was so down to earth and friendly and casual. They all were. It was a mighty pleasure working with them.

Taiwan.

Germany, went just as brexit was happening, loved the place and people were so friendly, had a few long conversations with people on the bus/train. Also best breakfasts anywhere.

Y'all can afford to visit another country?

Like you already wrote, Ireland!

It was kinda shocking how openly friendly and relaxed most people there are.

Yeah, I would say the same thing about Americans (yes I know you're Americans too. I think we all know I mean the US). If you meet MAGA on the street in a non-political way, they might be super nice. You might have a great interaction. I have traveled around the world and I maintain that food service personnel in the US are the friendliest. I'm guessing many of them are MAGA.

Turkey

People love to make exaggerated statements on the internet for attention but I can say very truly that the spirit of the people changed me inside and it helped start my sobriety journey

England. I got blind drunk and was stumbling back to a hotel in a western suburb. A group of young men with knives approached me for cash but when I told them to fuck off (not smart, I know) they were so excited to hear my accent they walked me a couple of blocks to the bus station and sent me on my way.

For me it was Russia when I spent aroubd 9 days there (in and around Moscow). The people were genuinely friendly and there we not the scammers/tourist traps like in most of Europe and Asia.

The markets were as interesting as any I've been to in Asia/North Africa.
