Gordon, that is your belief and you are more than entitled to it. However, your views of what is sin are irrelevant to me. Your worldview tells you there is only one way to believe, but in the here and now there are many people who disagree with you. It is not so much that other believe differently from you. What matters is how you reconcile yourself with that fact and how you deal with people who don't believe like you do or live like you think they should.
