I really have no dog in this fight, if only because I am one of those unfamiliar with with William Lane Craig. But if his views are as transparently false as Dawkins claims, why not confront him and demonstrate that in debate? As I read what Dawkins quotes from Craig, it seems that Craig is not defending genocide, but defending God against the charge of genocide, saying that genocide is not really what God commanded. Surely that interpretation is debatable. And in fact Dawkins raises an objection to it in this piece.
