I think what Dawkins meant was that he's for teaching kids how to think critically, and not necessarily WHAT to think. I think the question isn't very clear, as I don't think there is no real consensus on what atheists do with their children. Some can brainwash them, some can leave them be.
Why would it be important? The only important factor would be that the kids learn how to use reasoned logic and apply it to every facet of their lives, which is possible in any situation, however unlikely the circumstances may be.
