States rights mean the state has the right to take away individual rights. I'd love for someone to articulate a non-religious reason for banning same-sex marriage.
Less cheap labor from prison.
Explain
Sorry, should have said more cheap labor from prison. Make sodomy illegal, you get more prisoners. Gives more government cheese to your donors in the prison industry and also gives them more free labor to exploit.
Another benefit would be that spouses can collect social security after you die. So it saves the government money if you can't have a spouse or adopt children.
