It seems a bit as if you're not reading my comment in the context it was intended for.

> Mars is more livable than the moon because it has atmospheric CO2, (more) water, and a better mineral story.

The post I was answering posited a Moon base first because it's a less ambitious test bed, and I think that is largely correct. I was not making the case for a self-sufficient Moon colony instead of colonizing Mars.

> it's clear that nothing which filters down to the parents could be called anything close to known (much less absolutely).

It is very hard to make that argument convincingly in the face of, say, honor killings. Yes, theoretically you could argue that parents who intentionally harm their child technically do not "know" any better. But if we are talking on that level, that is certainly not an argument in support of why giving birth to a baby on Mars is somehow worse.
