There is nothing in my post or my subsequent comments about needing to increase the population. We don't need new humans because we have too few humans - we need new humans because old humans die.

Policy are supposed to get judged by real world effects. If we want a certain number of new humans those people who want to go through the experience of childbearing should start producing children. In the present world those already produce too much children, so there no case of the people who don't want to produce, to produce.

I do have particular counterarguments to that (including the quasi-racist stuff you'd expect) but it's also just a turn in the conversation I didn't anticipate at all.

Giving that you do point to the quasi-racistic stuff you are basically holding the position that not everyone should get children but that the right people should as Mestroyer said.

In that case you just disagree with him about who the right people happen to be. He thinks it's about being intelligent and the type of person who goes on lesswrong while you might also want more of stupid people that share your racial identification.

Without restricting the arguments to being about the right people getting more children the case is easily dismissed in a world with overpopulation. In the spirit of fixing the arguments of other people it makes sense to treat you as saying that you want the right people getting more children even if you don't explicitly say so.
