DJW,
There is widespread belief that atheists are untrustworthy and lack an objective moral compass. However, I have seen a great deal of evidence to the contrary in bold comments by Cofty and Simon over the years. I usually don't weigh in on these differences among atheists, until now.
Other atheists on this board (certainly not all) seem to promote the subjectivity type of morality, which leads to absurdity as I have tried to demonstrate.
I have also seen marked differences between European atheists and American style atheists.
There are reliable similarities as well as differences between believers and disbelievers in the moral values and principles they endorse. And, that is what I'm trying to explore.
