To go along with that, there are also significant problems with scientists trying to say things about religion. 

The atheist biologist P Z Myers responds to statements that atheists don't know much about the religion they are attacking. He calls his response the "Courtier's Reply", which refers to an imagined defense a sycophant might give of the naked emperor of Hans Christian Anderson's story: "Haven't you read the discourses of Count Roderigo of Seville on the exquisite and exotic leathers of the Emperor's boots?" and so on. The idea is that complaining about an atheist's lack of theological knowledge is no better than the courtier's complaint that the naked emperor's critics haven't read the works of Count Roderigo. In other words, it is just the same old question-begging "Pastafarianism" pseudo-defense, now tarted up with a clever marketing tag.
