One of the more popular criticisms of Muslims that can be found within the atheist community takes the following form:
Sure, not all Muslims commit acts of violence; however, they do not speak out against it, because they know that the violent actors are adhering to the true nature of the religion.
The latter half is omitted as often as it is included, but the subtext of “moderate Muslims don’t speak out against violence committed in the name of Islam” does not really permit many interpretations beyond that conclusion. It is seemingly predicated on a belief that a plain-text reading of the Qur’an leads to the clear conclusion that violence against non-believers is permitted.
Never mind, of course, that the opposite is true.
