The crutch argument has always struck me as incredibly idiotic. Everyone, regardless of whether or not they have a self-identified religious affiliation, has a "crutch" to get through life. Everyone develops coping mechanisms to deal with stress. Everybody. Everybody has these "crutches." I strongly prefer to not refer to these crutches in a patronizing fashion, because it's disrespectful and rude. It's especially rude when a specific group of people is singled out for having them when, in fact, everybody has them. It means group A wants to rationalize that group B is inferior, and that's about it. Ironically, you could say that is one of their crutches: the need to feel superior to "those stupid theists."
Now, if we want to talk about unhealthy ways of coping with stress, that's a different discussion. We could talk about things like addictions to substances. In that case, the patronizing term "crutch" might be more appropriate, but probably still misleading.
