All you're saying is that if I don't agree with your religious views, I can't make moral judgements, because morals MUST come from YOUR God.
Nice try. I don't buy it. And I'm not convinced your pipeline to God is any better than mine. Care to show me why yours is better ?
Morals can also be established by other means - harm to one's self, or another, for instance. This doesn't require ANY religious belief - just a little thinking.
Arguments regarding ethics derive from the First Principle that the good is to be done and evil avoided. (Such arguments are also consonant with divine revelation, since the God of Reason is also the God of Revelation). Read Aristotle and Aquinas.
