Maybe you can help me figure out your logic here. First, the reasons offered for this position include climate change and vulnerability to disease. How do these not apply to the wanted child described in the next paragraph?
And perhaps more importantly, do the rules of immorality apply to the born child who is not wanted? A hypothetical 2-month-old who was not planned and is not wanted by her mother, if her existence is immoral, can we apply the same logic and expel her from existence? If not, why? What is different about her?
