If you read my comment, I didn't say not having kids itself is a moral weakness. I said that moral weakness leads to a lack of desire to reproduce.

I don't see how that follows, either,to be honest. There is no shortage of immoral parents

You're thinking in odd absolutes. I would call strawman but I think you're doing it in good faith anyways

You are asserting that moral weakness leads to a lack of children, with no exanation. I said that I don't see how that follows, and plenty of morally weak people have children. I don't see how I'm attacking a strawman by giving a counter example, you've given no reasoning for your statement

How is it not? The matter is obviously a personal choice and there are certainly exceptions, but in my opinion raising the next generation is the most important thing one can do, and willfully ignoring it is selfish.
