No, that is not my answer- you are stating what you want me to believe, not what I actually believe. I agree that we are endowed with inalienable rights, I just don't believe in the existence of a creator.
Your argument seems to be that it is impossible to be a good American unless one is a Christian. That is utter nonsense.
You can believe whatever you want but this country was founded upon the idea that rights are inalienable because they come from God. You don't believe that, so you don't believe in America. Period.
