Well, I was not born here and have been asked millions of times where I’m from and I have to say I have never, ever encountered any outright meanness or any under current regarding my origin. No prejudices, no insinuations, no generalisations. Everybody I interacted with has been very welcoming and the majority of people have surprised me by actually taking the conversation further and highlighting lots of positives about my country of origin and the people of that country, sometimes niche information. People I have interacted with across the UK are far from ignorant, are very welcoming, very polite and certainly make up their own mind about any topic. And let me tell you, there are a number of well known negative issues from my native country but individuals within the UK have always treated me with utmost decency and had lots of good things to say about my country of origin.
Where I live, it’s like United Nations (transient and well established residents), the road I live on, at school gates, in the parks etc , even dog pets come from places anywhere between South America and Turkey via Italy. Everybody asks everybody (eventually) about where they are from regardless of their own origin. It’s chit chat which sometimes turns into a very interesting and fascinating long conversation. The other day I met a young Hungarian lady complete with imported dog, it was really nice chatting to her and learning about her country and culture. And I like telling people about my birth place. Some people are of mixed origin and have lived in lots of countries, I could talk to them all day long about their experiences and family heritage. And I’m not unique in any way, there’s nothing special about me, as ordinary as they come. Other people feel the same as me.
I get asked where I’m from when I go to other countries so it’s the way people try to make a connection in some cultures, I don’t see it as an intrusive question.
So my comment is based on long term personal experience.
However, I appreciate that other people feel differently because they feel this to be too personal a request of information because that’s how they feel. I’m sure I have other things I’d find to be intrusive or rude but others are OK with them.
