These kids were not allowed to sing "God Bless the USA" at school so they went outside to sing it. And they met adult hecklers.
The man with the dark colored shirt told the kids they were going to "burn in hell". Another man said "What does the red, white, and blue mean? Nobody knows".
Vann said this. (Starting at 7:05.)
Why would you make them sing the song they aint even a part of. They ARE Americans nobody is doubting that. We all know you are Americans… BUT they should not be allowed to sing the song that is above their age group. As a parent, I don’t believe in it.
Here are some comments from Youtube.
