Yeah there's not usually malicious intent behind it and my first reaction was similar to yours, but then they said: "I bet no one's ever said that to you?"
And it's true. When people ask where I'm from and I tell them, they accept my first reply. But when people don't accept their first reply (i.e. "I don't mean where you were born, I mean where your family comes from") it shows they see them as an outsider.
I should have been clearer with the hair remark - it was said by a female black friend who said it's white girls who would touch her hair and say: "oh wow it's so thick!" And, while it sounds like a compliment, they wouldn't do it to fellow white girls' hair.
They're all subtle, small and insidious things, but they do make a difference. And my first reaction was to kick back, but then I thought... why am I trying to defend other people's actions? These are my friends and they're telling me something that they see as minor racism, why would I argue with their experiences and how they're made to feel?
I totally understand since I've experienced it as well. "Where are you really from?" is truly irritating when you state where you're born. I've even been accused (several times) of lying and offered to show some I.D to this one
mole who wouldn't leave me alone. Or "if you're from x"(I just said I have some ancestry not that i'm from there pr*ck) "how big is your d*ck?". I always get questioned about my ancestry ESPECIALLY in north america, by people I barely know (ex.i'm buying milk at a corner store and this asian lady harshly says ; where are you from? sometimes where are you really from, so I always say the same thing back).
So I only tell people I know well so even if some assholes/ignorants wanted to make a remark like that they can't do it as much. I'm lucky enough that my ethnicity isn't that obvious to many people so I can reduce the amount of racist assholes I run into. I could tell you more stories like the ones I've shared above.
I do think it can be a matter of context, (ex. I tell a friend my full ancestry and he makes the wrong assumption that I have heritage from my foreign ancestry, then we talk it out and he understands what I mean) but there's also some minor racism in day to day interactions.
That I believe, but when people say that institutional racism is a given for all POC, well I'd like someone to point it out, because I've never felt I've faced that but I might be missing something.
