Amen Court. There is a sort of cult mentality I've come across in some folks that parenthood is really only motherhood with a man who may (or may not) tag along for the ride. I'm lucky because though I'm sure my SO's family would be basting in joy if we turned traditional, got married and had a baby, they aren't saying a word.
V - your friends who claim choosing to have a baby is selgiraffe are nim-rods. Choosing to be a parent can come from an egotistical space (the world needs one more of me), but it can also come from an altruistic place (the world needs good people, I'm going to make sure I raise a good human to add to the betterment of society). I see choosing to be a parent as being hella' generous - anyone who puts much thought into it knows they will be giving up a lot. This is the strongest force that keeps me from wanting kids. I'm deeply satisfied with my life, and my art is so important to me that a part of me would die if I had to live a life where it played second banana to the role of motherhood.
Oddly the whole "the world's going to hell" thing has never been a part of the equation as to why I don't want to have babies, even though I often think it is doing just that. Probably because I've seen third world, fourth world, fifth world level poverty places, and hella' circumstances, and know that happy, decent humans are born into this all the time already, and that these happy, decent human beings live lives that are fulfilling to them. True, we North Americans, in large part, are privilege to a life of comfort and ease that is unprecedented, and I don't doubt that the carpet may be pulled out from under us all hella' fast. I totally agree that a big change is comming, but I have a lot of hope in the resiliency and adaptability of human kind. All my material things could evaporate tomorrow, and I know I'd still be laughing and telling stories, and be essentially who I am now. I've lived enough personal hell to know that even when it's all shit there's still possibility. Skip to a future where there's only a clutch of us humans left, and I don't doubt that their society would still have singing and dancing and that people would love each other and such. So what I'm saying is that I'm a post-apocalyptic optimist.
