'Manda posts essays online, wherein she makes it clear that she is an atheist. For example:
Prayer is a great way to pretend you are doing something about a problem, when you're not. Sometimes that problem is nonsense, like this trumped-up crisis that I don't bow down to a god so I'm going to be tortured forever after I die. Conversely, if the problem is real, then we've got an unhealthy situation in which you can avoid taking actual measures to correct it or at least discuss it with other human beings. Whether in public or in private, prayer is an extremely bad idea.
