Imagine a world where slavery, segregation, and racism had never existed. Imagine a world where interracial marriage had never been prohibited. Imagine a world where skin color had always been seen as insignificant as hair color, where the word discrimination still had a neutral connotation, where the idea of discriminating between one thing and another had not become tainted by the injustice of racism.
Imagine yourself in that world and ask yourself this question: Would same-sex marriage exist?
No, it would not.
