Atheists come up with ideal god

[TheRocketSurgeon]

Humans are capable of making laws up without God's help, but what I'm asking is if you think genocide, for example, is absolutely wrong. Or is it just a result of sociocultural relativism?

Ugh, saw this right before I went to turn the computer monitor off... so I'll answer.

Of course it's a result of sociocultural moral advancement, all of which are relative. That's what I meant by "two steps forward, one step back". Some societies get it wrong, and it's incumbent on those societies who have come to recognize the concept of basic human rights to step up and convince the others to come into the modern era. 

Unfortunately, ISIS is still living by the barbaric code that informed the Biblical authors' worldview. They certainly thought that Genocide was not just okay, but commanded by God Himself!

We know better now. Our relativist morality has expanded to include the basic rights of individual humans, at least in principle (our jurisdiction cannot cover everwhere, but that's why I am a Secular Humanist, a group whose beliefs include the idea of a single world government in which there would be universal rights and global jurisdiction to protect those rights against the remnant barbarities of selfish and violent groups, usually guided by Bronze Age desert religions in their reasons for acting thusly), and there's really no putting that genie back in the bottle, so to speak.

Every rule you think is "fixed and absolute" (and thus objective) has in fact changed with time. What constitutes rape has changed drastically, just since the 1970s in the USA alone. Murder may seem objectively wrong, but if you read any basic book on anthropology, you'll see that the exact definition of "justified" murder varies wildly across the globe. You might think stealing is objectively wrong, but the concepts for exactly what constitutes property and theft are a product of our particular sort of civilization, and again can vary widely... even we would not punish a child who steals because he is starving, for instance. We would consider it morally justified because of a failure to properly take care of that child, as we think adults should do... another idea which varies widely from culture to culture.

We get this question here almost literally every day, because there are preachers out there teaching that they have absolute morality and that we atheists can have no basis for it as relativists. But nobody really thinks it through, to realize that we are all  relativists, and that our relative definition evolves in each culture over time, with concepts bleeding-over from culture to culture and rights movements changing the entire landscape of what was once considered acceptable and moral.

The accusation that atheists have no basis for morality flies in the face of the fact that even animal societies can be demonstrated to behave in a self-sacrificial and "moral" way under experimental conditions, and that it is observed in all human societies, whether secular or religious, even though it varies and changes. Humans make rules. We make societies. We make morals. It is the fundamental definition of what we are: the moral, intelligent, social animal.
