Dawkins argues that his criticisms apply evenly to all religions and that he only focuses on Christianity as that is what he knows.
I have to agree with him to a point. Certainly the Abrahamic Religions do suffer from the same flaws. Hinduism and Buddhism, and the various Pagan religeons are different however.
Your right that the current crop of Atheist arguments do not necessarily apply to them. However that I suspect is that they are trying to change Western Society, and the other religions are not a significant entrenched force in Western Society.
