As the old saying goes, everyone is born equal. I actually agree the opinion in this song, love is color blind. We are the one, we are living together in this world. It's not necessary to separate the Black from other races.
Of course the singer's dream would come true one day. There are many international organizations in the world to fight against the racial prejudice. In the meantime, a lot of people are in favor of the campaign. I think the dream would come true one day.
