I hope not to sound like some sort of birth evangelist but could we not flip that statement?

That portraits a child as someone that you need to protect from suffering at all costs. If your parents were to make the same argument towards you, as an adult, you would argue that it is perhaps condescending and removes somewhat your own agency.

There is a _chance_ that any children that you bring into this world become not only an adult but an agent for (positive) change.
