Are atheists mean-spirited?

I'm sure there are plenty of tatheists out there who really could not care less that there are other people out there that believe in God, it's just that I don't run into alot of them on the internet. Much more often, I encounter the snarky know-it-all types who oftentimes refuse to answer hard questions concerning their own, pet beliefs when confronted with serous questions that challenge them.

In a recent article in World magazine, Janie B. Cheaney examines some of the circumstantial evidence that atheists tend to be self-absorbed and mean-spirited...

"Can I prove that atheists tend to hold a low view of mankind? There's plenty of circumstantial evidence. One is the position they stake out for themselves as more intelligent, courageous, and honest than the general run. Two is an argument that pops up frequently in skeptical circles: If God were such a creative genius, wouldn't He have done a better job? Especially with humans? Three is the scarcity of benevolent works founded by atheists. I'm sure there are some, but their names don't spring readily to mind like, say, Samaritan's Purse, Catholic Charities, and the hundreds of hospitals named for a Saint.

Seen on Answerblog.com: "How do atheists express their love for the rest of humanity?" Answer: "You don't need religion to express love, you complete idiot. Why are all your questions so ignorant?" Genuinely warmhearted atheists exist, but warmheartedness is not the first descriptive quality that comes to mind. The more vocal ones betray themselves sooner or later: To reject God is almost always to despise people."

The above quotation reminds me of a past entry by Vox Day who related..

"The atheists with whom I do have a problem, and for whom I regularly demonstrate a great deal of contempt, are the liars, the cheats, the deceivers, and the malicious. If one genuinely believes that religion is a crutch for the weak and psychologically needed, what does it say about those who are so eager to kick that crutch out from under those who clearly need its support? And, as an armchair intellectual, I find their willful ignorance of history, religion, and philosophy to be as astonishing as it is irksome. Intelligent? I don't even consider them to be educated. To claim that religion either causes war or is an important strategic element of war is to be every bit as ignorant as the apocryphal Flat Earth proponents so often cited; the significant difference being that the Religion Causes War Society not only exists but is even willing to expound their ludicrous and historically illiterate arguments in public."
