I posted this here: http://www.livescience.com/9910-humans-neanderthals-mated-making-part-caveman.html in reply to a person who called someone with a Christian world view an "asshole" but it probably won't be accepted by the moderators, so I'll post it here too. In reality, I've wanted to tell quite a few atheists this anyway, so here goes.
Try to remember that your manners represent your beliefs, or more accurately in your case, your lack of beliefs. Christians are fairly used to being insulted by educrats and their blind followers; seems like it's okay and even politically correct to insult, malign, and be prejudiced against Christians these days. But that's okay because they get points with God for being thus insulted, so it really doesn't matter. Go ahead, name call, insult, bully away, make a fool of yourself.
It just proves to Christians that you are bitter and depressed like you should be if you believe that life started accidentally from some primordial stew, which in turn makes humans accidental, parasitic animals with no reason to live other than to conquer each other in a futile effort to be the fittest survivor, and in the process are bound to destroy everything on the earth and then earth itself. Yup, makes perfect sense. I'd be depressed and angry too if I thought I was an accident and there was no reason for me to live and ample reason for me and my kind not to live. What a shame, what a waste, what a sad life.
Look at it this way: if you are right, and I am wrong and there is no God then there is no heaven and no hell and in the end, we both die and are dead, and that's that. Except for the fact that we've lived different lives. You've lived as if there are no moral absolutes, done what you wanted when you wanted with whomever you've wanted. In doing so you probably have unwittingly contributed to the decay of society simply by not adhering to a moral standard--you might have to think about that one for a while, but that's okay, save that for later.
I, on the other hand have lived my life adhering as closely as I can to a set of moral absolutes which are designed to protect and preserve human life and dignity not to mention make us good stewards of the earth. So hopefully I have caused less societal decay than you have, but even if I have flubbed up (and who hasn't?) I am forgiven by God and that forgiveness (love and acceptance) compels me to seek forgiveness and pay restitution to those whom I have offended. My "conscience" (Christians have another name for it) speaks louder to me than yours, because I developed the habit of listening to it instead of drowning it out with continuous thoughts of ME, MY, MINE, ME FIRST, ITS ALL ABOUT ME, WATCHIN' OUT FOR NUMBER ONE--ME! Yeah, I have news for you, its not all about you, but I digress.
Now, lets say I'm right and you're wrong. I die and I am instantly in the presence of God-in paradise because I acknowledge the fact that God so loved all of us that He sent His only begotten son (Jesus) to live, and then die for my sins in my place. You on the other hand, die and get to find out which level of hell you get to go to and then you get to stay and burn in that God forsaken place forever because you rejected your own God given conscience. You know very well what is right and what is wrong, that there is absolute truth, and that my friend, is another source of your anger and depression.
Doesn't take a rocket scientist or even an evolutionist to figure out which lifestyle is healthier and does the most good.
