I wish to discuss morals a bit, as it pertains generally to nearly all discussions we have here, though this is in response to no one person or post in particular.
Morals are one of two things (though I will actually argue for a third later): ambiguous and determined entirely by society; absolute and determined entirely by God. As I've stated before, the morality of certain actions is difficult to justify when one leaves God out of the picture (note: this is not an argument for his existence, just that something is not inherently right EVER without him). Let's talk about the biggest question of morality: human life. When can a person take another person's life? I think, apart from abortions, most of us agree on this. But when we discuss the why, it becomes a bit more ambiguous. Why is it wrong to murder? Someone (Leonardo?) mentioned that it's wrong because it is destructive to the overall wellbeing of our species. But this is clearly not the case. How often do we preserve life which technically is nothing but a drain on our species. The elderly offer little to the overall survival of humanity, the severely ill are a substantial drain, the mentally ill or physically or mentally disabled cost our society as a whole so much, yet give nothing in return. Where I work, there is a man so ill, lying on death's door, yet still alive for weeks and weeks. He has surely cost Medicare hundreds of thousands if not millions of dollars, yet he remains alive, and it would be wrong for us to kill him. Why? What does he give to us? It is wrong because either God said so, or because our society believes it to be wrong.
Why am I making such a big point out of this? Because the fact of the matter is that those who criticize religion and believe that harmony will come to the earth when religion is (peaceably, according to most) eradicated. What they fail to realize is that the very values they cherish, the very society they have adopted, the very freedom to exercise a belief in no religion, came from those before them who worshiped the Creator of Heaven and earth. Those who are sick of religion telling them what to do and believe fail to realize that their own social/political dogmas do the same. Sure, they are more liberal in their values, but who is to say that a different, future society won't find what present-day non-believers cherish to be outdated, archaic, even barbaric. One day, euthanasia may be commonplace. One day, privacy might be drastically inhibited in order to better preserve humanity. One day, eugenics, population controls, genetic alteration, sterilization, and other things we might call immoral horrors may be put into place because the fact of the matter is we can indeed better preserve humanity if we better controlled the whole of it. Sure, humans lose their individuality, but in return we gain security for our species.
Religion and nonbelief can coexist. In fact they must learn to, for neither will replace the other, unless I'm right and the Second Coming of Christ finally occurs of course ;) The fact of the matter is that both provide good, both can be moral, and both may see things differently. But just because those moral lines are drawn differently does not mean that they cannot ultimately work together for the benefit of all.
