There are scriptures that advocate that we respect the alien in our midst; that we not mistreat or take advantage of them. Instead, we first took advantage of them, and now we aim to mistreat them, and our governor who likes to make a big deal about his faith just smiles and signs the bill. Leviticus admonished the Hebrew people to “remember that you were once aliens.” All of us white Americans in the U.S. should likewise remember that we were once immigrants.
Roger Lovette, who has actually read the entire bill, has written an important piece on his blog Head and Heart. The title of his piece is "Wondering about Immigration - Sunset in Alabama?" He uses a beautiful poem by Langston Hughes as the backdrop for his comments. I highly recommend it for you reading. You can find the essay here.
