As someone troubled by the implications of religious dogmatism and the fundamentalism of many believers today, I offer thanks to you and Dawkins and Harris for challenging the tenets of biblical literalism.
That interreligious conflict has been a profound blight on human history, and that an overly rigid reading of scriptures has contributed to this phenomena in recent centuries can not be argued; but what you do not address in your debates or books is that religion is just a word we have always used for a social organizing principle and an individual developmental framework - something to bond communities together and a system of rituals, practices, and processes by which individuals develop through the stages of life. These are needs addressed by religion, clothed in allegories and myths, but also inculcated as practical living processes.
Marx may have called religion the opiate of the people, but he also acknowledged that you can't do away with it unless you address the framework of society that caused the need for it in the first place (in his view, capitalism - in others' human nature, the innate need to balance community and autonomy). Marx offered socialism as his cure-all, but obviously this has not cured-all...I just wonder kind of debate you and your Bright-brothers would offer up against a Karen Armstrong, say, or the late Joseph Campbell, scholars who recognized the pedagogical, pragmatic, and emotionally nourishing qualities of religious life, emphasizing, in the former case, the practice of "spiritual technologies" like the Golden Rule, inner contemplation, and universal compassion.
I think you lose a lot of credence when you focus only on the mythical nature of...myths, and do not recognize that you are addressing a symptom of the degeneration of religious systems rather than honoring what is at the core of their reason for being - an evolutionary impulse towards greater stages of moral development and collective community.
