The separation of church and state is set in place not just to protect the state but to protect the church as well. To protect the state from allowing religious views to dictate government rhetoric but also to protect the church from having the government tell you who you must accept. It allows you to have your exclusive club of straight people and allows you to refuse to marry anyone you do not want to marry regardless of who is legally allowed to be married. Total equality in government does not change who your church or religious organization can exclude. Total equality in government simply makes us all people. Simply being viewed as human as everyone else by your government does help people understand that we are all just as protected by law as anyone else.
We are not voting to marry same sex couples, we are voting to single out a group of people and remove them as equals justifying the hurtful and violent actions of those that would do so.
