If what you’re saying is that people ought not to see children as “things” which are brought into being in order to satisfy our own self-centered needs, then we’re in ageement.
What I’m saying is that the reasons given by many people for having kids are often at least as shallow as they claim the childless are. That bringing people into existence just to take care of you in your 70s is lame, that genetic immortality is a sad motivating factor, and that because the people who throw these reasons around are also quick to scorn others I enjoy scorning them right back.
