AITA for speaking Italian to my boyfriend’s very racist grandmother and confusing her?

My(25f) Italian and I’m very proud of my heritage, I’ve travelled the world (but haven’t been to many places in Europe). I met my boyfriend while on holiday in Switzerland. He is from a small town in Germany very close to the Italian border, everyone there speaks Italian as well as Swiss German. <br><br>When I met him, it was very clear that we were from the same area, both by accent and the dialect we spoke. He asked me if I was from South Tyrol and I said I wasn’t, I was actually from Italy. <br>After going out for a few weeks, my boyfriend said he wanted to introduce me to his family. <br>I was very happy to meet them and while chatting with his mother, I asked her what should I bring with me. <br>She told me his very big Italian hating grandmother lives with them, she would be very angry if I showed up speaking Italian so I should speak in English or German instead. <br>I was very very surprised when she told me that his grandmother hates Italians, I asked her why and she said she doesn’t really know, all she knows is that she doesn’t like Southern people, especially the Italian ones. <br><br>I thought that this was very racist and I didn’t want to feed into her racism, so when my boyfriend came to pick me up, I asked him what she would think if he showed up speaking Italian. <br>He said she would start a big fight, she would call me a disgusting Southern s**t and all the other horrible things so I shouldn’t. <br><br>During the entire car ride, I practiced my very bad Schwäbisch and once we were there, that’s what I spoke until his grandmother showed up. <br>Once she showed up, I stopped and started speaking in Italian. <br>She was furious, she called me a s**t and a worthless Italian, then I responded in perfect Schwäbisch that I was very disappointed, I thought she’d be happy to speak to an Italian like this. <br>She was so confused, she asked what I meant by that, my boyfriend’s mother told her I had been speaking in Schwäbisch the entire time. <br>His grandmother was so confused and embarrassed, she ended up apologising and not leaving her room for the rest of the evening. <br><br>When I told my boyfriend and his mother what I had done, they told me she was going to go after me with a pitchfork if she found out so I should never tell her. <br>She found out when my boyfriend’s uncle guessed it. <br>His grandmother went to my boyfriend’s mother and told her that I was an AH for doing that, she was just trying to teach me a lesson when I was being a rude AH and that what I did was very mean. <br>My boyfriend’s mother told her that she shouldn’t call me horrible things just because of my ethnicity. <br><br>All of this happened a week ago and my boyfriend and his family haven’t mentioned it again.
