And they are! Just yesterday I was hanging around with a bunch off atheists and they were all pretty angry. They were even getting angry with each other. I could hear "get off my lawn" as a more or less constant droning sound in the background.
People who are not atheists, or who may be indifferent to religion but never thought about it much, might want to know what this is all about. One way to do this is to read a book that just came out, literally about five minutes ago, for the Kindle. This book is by my friend Greta Christina, and it is called Why Are You Atheists So Angry? 99 Thing That Piss Off the Godless.
I've seen Greta's talk on the topic, and it is spectacular. I've read some of this book in draft form but it's too new for me to have read the whole thing yet, but I will shortly. Meantime, I thought you'd want to know about it right away. You will enjoy it no matter what your perspective on religion is; the book is well written, engaging, funny, detailed, compelling and will make you mad.
Get off my lawn!
