Morality must relate, at some level, to the well-being of conscious creatures. If there are more and less effective ways for us to seek happiness and to avoid misery in this world - and there clearly are - then there are right and wrong answers to questions of morality.
In my own case, the most inflammatory statements I have ever made are ones that I have written and remain willing to defend.
The usefulness of religion - the fact that it gives life meaning, that it makes people feel good - is not an argument for the truth of any religious doctrine. It's not an argument that it's reasonable to believe that Jesus really was born of a virgin or that the Bible is the perfect word of the creator of the universe.
