Religious faith is, precisely because we are still-evolving creatures, ineradicable. It will never die out, or at least not until we get over our fear of death, and of the dark, and of the unknown, and of each other. For this reason, I would not prohibit it even if I thought I could.
So this is the reason why Hitch would refuse to eradicate religion in a snap of a finger if he could; not because he likes to argue, as Dawkins usually claims lol
