AITA for asking a date where he is from

AITA? Repost cause it got deleted Throwaway because I don't use reddit, just lurking. I want to preface this by saying two things. I am not a native English speaker, so I apologise for any weird phrases or wrong words. Second, and important to my story; I am legally blind. I have RP (retinitis pigmentosa) and in addition ~-4 on both eyes. I am able to type this with both the speech to text function and other various helping functions. In real life I wear a cane but otherwise I am independent.

Now,i say this, not as an excuse, but to justify and underline my side of this story.

I (f24) recently started dating for the first time. I didn't know how to get into it, so my friend suggested her putting me up on a blind date (haha) and I agreed. She gave me his (m26) name, and we agreed when and where to meet. It was a nice and warm day, although a little snowy, so I decided to get there a little early incase it would be hard to navigate myself. I found the restaurant (I've been there before) and sat down at the booked table.

The guy shows up and we start chatting. I pick up a slight accent, and ask where he is from. Now here is where I might be the AH due to my phrasing. He laughs and tells me he's "local" And I giggle and push it a little more saying "haha no I can tell you're not from here". The guy stops laughing, silently gets up and leaves. Im confused, and sit there for a few minutes waiting, incase I misunderstood the situation and he went to the watercloset or something, but he doesn't come back, so I pay for the drinks and cancel the food, before getting up and walking out.

I call the friend who set us up once I'm home, and she tells me "he thought you acted like such an asshole." I was apparently rude as fxxk, racist and was looking at anything but him during the conversation. I am so confused

The last part I can understand, as me being blind makes it hard to understand what om looking at, but the rest leaves me super confused.

Here's where I could be the AH. My friend also explained to me in our call that he is from the same country as me (although from the part where they also speak another language) but he is darkskinned and adopted from birth. Have I accidentally said something racist?

AITA?

Tl;Dr, I was called a racist and I do not understand why
