Atheism Cannot Rationally Explain Morals.

Not exactly. Society's morals are influenced by history and culture as well as by current opinions. The "right and wrong" that we learn can change as we are exposed to different ideas and different cultures. The idea that it's wrong to discriminate on the basis of race, gender, sexual orientation, etc. is much more recent than the idea that 's wrong to kill or steal.So it isn't "whatever you want it to be". It's whatever has been assimilated by your culture.

Monogamy seems to be an obvious example. We all "know" it's "wrong" to cheat on your spouse, boyfriend/girlfriend, etc. but cheating is very common. I don't know about hat. I'd say that rationality is about what we think; it has little to do with what we do.

On the contrary, we define our own meaning instead of having "meaning" spoon-fed to us by some alien overlord. As I define meaning, not only are my children more important than bugs but they're more important than you.

On the contrary, the collective morality of the place where I actually live is far more reliable than the opinion of some spook (who may or may not even exist). As Thomas Paine said: people can manage their own affairs better than some goober an ocean away. On the contrary, evolution suggests that our genes are important, so our children have to be protected until they can pass them on. That's the foundation of all morality.

So, do you advocate capital punishment for women who have abortions?

They think they do. That's all that matters. Whether the human will to survive is based on some woo-woo "meaning" imparted by some alien overlord or whether it's just a blind, mindless, unconscious and uncaring "desire" to pass on our genes, it's all that matters.The fact that we want to survive and we want our children to survive is all that propels morality. Even kowtowing to an alien overlord is based on the same will to survive.

What about imprisonment then? If abortion is murder, a woman who obtains an abortion should be treated as a murderer, shouldn't she?

Inferences are often wrong, particularly when the people making the inferences don't know anything about the subject. Almost every post you make is testimony to that.For example, a "primitive" tribe might infer that a man with a flashlight was a god.

If that mindless falling rock lands on your house, doesn't that have significance or meaning to you? Do you really need an alien overlord to tell you whether it does or not?

Evolution is about survival of the species, not the individual. Any behaviour that advances the survival of other individuals in our species advances the survival of the species as a whole.There is also the obvious advantage that even if we do die as individuals, there are other members of our species, whom we have helped to survive, to help our offspring to survive.

Everybody is guilty. The command to love your enemy underlines the fact that there is no difference between friend and enemy. Everybody is your friend. Everybody is your enemy, including (especially) yourself. On the contrary, we are to give aid especially to the ones we perceive as enemies.

Non sequitur. Weather is blind, purposeless, mindless and unconscious but it's still about movement of air. The beginning of a life may be a result of sheer, meaningless luck but the end of a life is the result of selection. It isn't just luck that the slow zebra is the one that the lion catches.

It's almost a certainty.

You have the wrong idea about "correctness". There is no absolutely correct or incorrect handed down to us by some alien overlord. What is "correct" in a given situation is what works in that situation. Since situations vary from place to place and from time to time, it's only natural that morals also vary.

Do you think it was absolutely wrong for Hitler to kill millions of Jews and absolutely right for the Allies to kill millions of Germans?
