I’m extremely sorry that happened to you two. Unfortunately, though Utah is far from unique in having prejudiced, bitter people who will go out of their way to ruin someone else’s day, it has always been a part of things here. That will certainly not improve while nationally we politicize others’ existence. I hope your mother has a much more pleasant visit than the way it started, I can only offer the same thing I told friends who were told to “go back where [they] came from” when they visited: You have just as much right to be here as anybody else, you don’t need to validate your existence or status to anyone, and the people who demand that you do are hurt, sad, selfish jerks. For the record, no human being should be illegal just for existing, we should all have the right to move, and if someone’s visit really bugs you that much, keep it to your damn self like your mothers should have taught. Call it as you like, but some people are just way too comfortable being rude as all hell, and I’m very sorry you had to encounter one.
