Lift Every Voice and Sing
This is known as the black National Anthem. This song was written to take part in a ceremony celebrating Abraham Lincoln's birthday back in 1900. It was written so that black people could show their patriotism for America and hope for the future. I guess back then to some the only "true patriots" were white people.
If someone were to sing this song today, how would it be taken. Oh wait, someone has, and as per usual they were seen as a hater of America and unpatriotic, obviously from people who don't know the history of the song.
This is why people should learn ALL the history of America, but to some learning all the history of America is a bad thing.
