"I don't think people who are scared of death should have children. What's to be scared of?"

Are you kidding me?

Depending on the wording of the poll, between 30 and 70 percent of people are scared of death.

I think your criterion of who should have children is silly.

By the way, if you were to discover that religious people are far, far less afraid of death than atheists and agnostics, the former looking forward to a glorious eternal afterlife of loveliness, would you still hold on to your have-no-children decree?

Being scared of death is perfectly reasonable if you enjoy being alive and you do not enjoy the idea of non-existence.
