Sorry to hear that, but can you quantify it? Like, do you get verbal abuse at work 5x a day, sneers at the grocery store every time you go, or what? Or are you talking about online talk about your identity? (I hate to break it to you, but with that last one literally every human being on Earth can find a metric ton of online abuse directed at them if they look for it.)

What people say about you (or your ethnicity) is orthogonal to the reality. Its hurtful only insofar as you attach yourself to their perceptions, and people are fundamentally ignorant. One of the things people seem to forget is that humans are by default deeply bigoted (and authoritarian). It's a miracle that there exist any places on Earth that have managed to curtail those instincts. If you live in such a place (and I'd count America, even Texas, as one of them) count yourself lucky. Let ignorant people flap their gums; it's hot air, signifying nothing.
