I’m sure it gets annoying and happens to you more. I’m white from the US and when nationality history was brought up I mentioned that I have a lot of Irish and other euro mix. Then they were like, wait do you aren’t American?

I had to explain basically everyone in the US is “from” somewhere else if you go back multiple generations. So people think this way even if you are white and they find out more info, but just assume “full American” until then.

Side note. I’m from southern California and among other things am craving some legit tacos.
