WHAT WOULD YOU HAVE DONE?

So me and my family went to corpus christi this summer and some white family (no offense) sat in the table next to us at the beach and they started laughing and turning to see us alot and calling us wetbacks and idk what else. I dint really care BUT my uncle stud up and said "I can understand you you ****** retards just because i'm latino/mexican doesnt mean i dont understand english" and then for some reason they dint even turned to see him they just sat there like trying to avoid my uncle and they started playing some game they were playing.. But we had to leave the beach because my uncle was really pissed off and my family agreed to just leave! I JUST WANNA KNOW IF THIS WERE TO HAPPEN TO YOUR FAMILY WHAT WOULD YOU HAVE DONE???
