Well, I'm not an atheist, nor particularly angry in general (unless you start talking child rape). But those are all good reasons to be angry at certain religiously motivated groups and individuals. My Master is an atheist. His dad is a Methodist minister. So they have a few interesting discussions at family events sometimes when Master asks his dad to defend religion in the face of these abuses, and really there is no defense. Which his dad, being a kind, compassionate and fair minded person, will readily admit. Basically, he says, there are a lot of people out there using religion to justify their own twisted and horrible ends and goals.
