I don’t think that not wanting to have kids must be condemned. There are lots of reasons one decides not to have a family. Having a child and raising it is a tremendous responsibility, and some times I think that most people are so irresponsible that they should have their genitalia removed and not be allowed to be parents. And I always thought that it is kind of weird to need permits for all kinds of stuff, like driving, or hunting, or even buy beer, but no permit whatsoever to become a parent.
I know that there is no manual to teach someone how to be a parent (and, a GOOD one too), and you learn as you go along, and try the best you can do, but I think that I shall agree with Fox. The world we live in is a terrible place. And rather than have a child and watch it get killed, or raped, or whatever horror this world can bring, I rather never have one. I know it is not exactly a rational way of thinking, but that is just me.
