The biggest problem is that his premise is wrong: evolution is not just about spreading one's DNA, as evolution happens to populations and not individuals. He's really talking about survival of the fittest, in that special, misrepresentative way that christians do, which doesn't take into account that "fitness," for humans, is about our ability to maintain a social species and not just outright strength. Rape, under the actual definition of fitness for humans, is demonstrably bad for us at the scale of populations, to say nothing of the individual harm.
Garbage in, garbage out.
