Can I embrace my heritage?


Sorry I wasn’t sure where to post this. My mom has biological parents where one is full Mexican and the other is full Italian, making me a quarter Mexican and a quarter Italian (right?). My question is, is it alright to say I’m part Mexican? Part Italian? Or am I not enough of it? I’ve always been fascinated by their culture and want to learn more about it but idk if I can say that I’m part Mexican. I just don’t want to offend anyone or people think less of me because I don’t look the part. The rest of me is a mixture of little things but basically just American
