 Wednesday night was the final Democratic debate before the March 15 Primaries, and it was heated. However, the biggest controversy of the night didn t come from the candidates sparring with each other. It came when a Mexican-American teenager sang the National Anthem at the beginning of the debate. Apparently, white America believes only Caucasians are allowed to sing that song.Fifteen-year-old Sebastien de la Cruz took the stage before the debate and sang a beautiful rendition of our national song. He has an amazing voice for someone so young and of course, given the fact that it was a Univision debate, it made sense that a Latino/a give the performance. Racists, however, weren t interested in praising the child for his vocal abilities or using common sense; instead, they decided to spew hate all over Twitter, because they are a$$holes.Here are some of their responses: .CNN this is the dumbest thing I ve quite possibly ever saw. For a minute I forgot I was in #America until they sang the national anthem.

In 2013, the then 13-year-old sang the  Star-Spangled Banner  before Game 3 of the NBA finals and the scummiest Americans reacted in the same way. They called him all sorts of names, but his response was perfect:  My father was actually in the [U.S.] Navy for a really long time,  De La Cruz told San Antonio Fox 29 in an interview about the backlash.  People don t know; they just assume that I m just Mexican. But I m not from Mexico. I m from San Antonio, born and raised, a true San Antonio Spurs fan. Fortunately, the positive comments far outweighed the negative this time around. Sadly, though, he will probably always be the target of scumbags who hate him just because his skin is tanner than theirs.
