Many primitive philosophies (religions) are (in their way) smart to pursue not only convincing folks of their strong cosmogeny beliefs, but also of their moral high ground. In fact, I think many people, even when they realize the biblical cosmogeny is (or may be) partially or fully nonsense, reconcile this with thinking that either it is useful metaphor, and/or that having and living a moral life is more important than anything (including the details of some creation debate). I think they fear that they may not be able to reason out either a rational view of the universe, or of the best way to lead their lives in it, on their own, and they concede the point to peer pressure and their own doubts, as to being willing to adopt the community standard beliefs.

I think a lot of atheists get at least some of this. However, on balance, I don't see too many atheists questioning why a concept (and robust thinking through) of "morality" is (or is not) a thing that is needed in our lives. Many do either assume or conclude (for those that question it first) that such a thing as "morality" is important to them, but then I am not sure how many question mainstream handed-down second-hand thinking as to what is and is not moral.

Fwiw, I think hashing out these matters over the years is one of the most useful and important things that we can do on this website.

Fundamentalist Christians take extreme offense when I point out the immorality of their God. They get even more upset when I point out their duplicity when they claim that their God has the right to be a genocidal maniac.

Most religions morality comes from fear of punishment and hell. I would say a no religious persons morality is even more sincere because it comes from the heart and not forced through fear

Religion is evil IMHO.

That bit about if "If you don't fear hell what keeps you from breaking into your neighbor's house and beheading them and raping infants?" Close to the Duck Dynasty quote.
These thoughts don't enter my mind.

Do unto others as you would have them do unto you has worked for me forever. It seems all religions have something similar as part of their teaching. That always brings up a question in my mind regarding their source.

I've found it to be a common theme amongst religious types that they feel that Atheists are more likely to be immoral, untrustworthy and even prone to criminal actions, this has been born out in numerous polls and studies. It's one of the reasons why so few politicians who are Atheists will publicly assert their true position on religion, most dodge the question if asked for the reasons cited above.

If had these discussions. I end them quickly by saying "I am sorry to hear you can't figure out what is moral without consulting a religion.

Arthur Clark is correct. There are no gods (or god) that gave you morality and the argument is lame. The biblical god is immoral and only a fool would see it otherwise. What bothers me with this is all the people who claim "I can be moral without god." Why is it an issue and why am I worried that I am not moral?

Another similar issue is Pauline believers that argue their god "gave them a soul" when bible study shows this to be breath. Yes, with the breath of life you became a living soul. When you die you will be a dead soul. If you are Paul you "cannot tell if you were in or out of your body" when you received important teachings. Modern believers just love this.

One of the problems with a faith-based morality is "What happens if I lose my faith? Do I also lose my morality?"
