The US Constitution recognizes the preexisting right of people of faith (or no faith) to practice their faith according to the principles of that faith and the dictates of their conscience WITHOUT interference from the government.

As a Christian, I am told in very strong language to "FLEE sexual immorality" which includes far more than homosexuality. Like the Corinthian church members, I can't say "Well, I'm not doing it myself, so it's okay for me to approve (or seem to approve) of another's sin." NO, IT IS NOT! The Bible is clear that it is not. I can ignore what the world does outside the doors of my home and the church, but I am responsible for my own walk with Christ and answerable if I present a false image of God's standards.

It's all there in 1Corinthians, by the way. What you folks do outside in the world is not my concern. What you do in my church or force me to participate in is very much my concern.
