All of the above. When I am angry concerning the topic of religion, it's typically because either (1) believers are doing shitty stuff in the name of their religion, while claiming all the positive accomplishments of the world as their own, or (2) believers are telling me I eat babies, or should logically want to eat babies, or (3) I think about how believers tried to cram their shit into my head at an early age, and how fortunate I am to have escaped it.
Mostly, I try to stick to learning new stuff because that always brings about the wonder side of things.
