Yes, it's hard work, and I was very happy to change my last diaper. But the rewards far, far outweigh the costs. Children are on balance a true joy, their laughter and smiles so pure and wonderful, that I can't imagine life without them.
I cannot think of worse advice.
Congratulations to you that you found a life that works for you.
But the idea that people should just stop thinking and start procreating is absurd. Kids are a gigantic decision, the biggest one a person will ever make in their life. To not carefully consider that decision is utterly irresponsible, and to tell people to thoughtlessly have children without considering those consequences is equally so.
2. It is not full of "coded bigotry." These are simple fact that almost everyone agrees on. India has explicitly made it a goal to reduce their fertility rate over the past few decades because of the problems of overpopulation. China's economy absolutely benefits from a high population. And yet I doubt you would characterize their humans rights record as stellar. It does not mean that Indians or Chinese people are in any way inferior to Westerners. And I highly doubt that the OP would agree with that either.
3. Even if it was, that isn't a critique of the comment's argument. It just means you find it distasteful. So what?
Yes, it is.
The core of their comment is "oh noes western values will be lost!" (Or as they put it: "the global West has values worth preserving for the future").
My point is, no, they won't, because fertility is dropping everywhere. We're not that special. And that this purported fear is simply rooted in age-old racist tropes of a loss of cultural identity to scary foreigners, nothing more.
