When Twitter user "Grace Kelly" saw 11-year-old Sebastien De La Cruz singing the Star Spangled Banner at Game 3 of the NBA Finals dressed in a mariachi outfit, she wrote: "I'm highly upset that THIS kid is singing the United States National Anthem. Clearly from Mexico..."
"Fracnois" wrote "This lil' Mexican snuck in the country like 4 hours ago now he singing the anthem."
Ben Koeck wrote "This kid is Mexican why is he singing the national anthem. #yournotamerican #gohome"
Needless to say, many Americans are shocked to hear these tweets and that such racism still exists.
Gavino Fernandez with the League of United Latin American Citizens says De La Cruz's mariachi outfit wasn't really on his mind while watching him.
"To me it was more of astonishment that the young man could hit the high notes that he did and how successful he was," Fernandez said.
Fernandez says the fact that there were so many negative comments is sad but not surprising.
The only shock is that so many of the comments were coming from young people.
"The generation that was making those comments did surprise me because I think that we had grown up a little bit beyond that. Unfortunately we're not but we're still working real hard at it," Fernandez said.
We asked FOX 7 viewers on Facebook what they think. Commenters showed resounding support for De La Cruz.
Johnny writes: "There's been talented stars that have butchered up the National Anthem....give the little guy a break."
Jessica writes: "I'm appalled... How can these racism comments still exist in this world of ours?! It's 2013 and people just need to worry about the horrible things going on in our world today instead of this little boy, who is obviously very proud of his heritage as anyone should be. Come on people! Grow up!"
Fernandez says educating people is the answer.
"Education to people in general that not all brown people are illegal. The population of our community has grown tremendously, the Latino community that are American natives. And we have served and continue to serve our country. And we are strong patriotic Americans like everyone else regardless of our color and regardless of our culture," Fernandez said.
De la Cruz seems to be handling the situation well. He was asked to perform the anthem a second time at Thursday's Game 4.
