To those who vehemently oppose the notion, is it because you're single, gay, feel you're not worthy, and have thus resigned yourself from having kids because it doesn't seem "on the cards" for you and therefore find it easier to dismiss the possiblility?
Well I don't know that I would class myself as "vehemently oppose[d]" to parenthood, but I'm pretty happy that I wont ever be one.
I love my life, it's taken me lots of hard work and lots of blood, sweat and tears, to achieve what I've achieved. Having had a a good bit of practical experience of what it's like to look after a small child I know that it's incredibly time consuming and hard work, I also know it takes a certain kind of temperament to be good at it. I also know that it totally transforms how your life is lead.
If you add to this knowledge that fact that as a general rule I don't really like spending time with children; I get kinda bored and irritated by them after about 10 minutes, and the certainty that I would be selfish and emotionally distant father, I really think that it's a positive decision and a best for all concerned that I don't have any kids.
For me children have never been a part of my life plan, not once in all my life did I ever stop to think about the possibility of figuring them into my plans. I don't think about having kids, I don't regret that the plans I've made for my life do not include them.
I suppose I'm just not orientated towards parenthood and that I tend to forget that children even exist, which manifests itself frequently when my friends with children have to remind me that no they can't attend my big birthday shindig in Lisbon because they wont be able to get anyone to look after their kids for 4 days or other similar lapses in my ability to recall that other people have commitments to their offspring.
For me the lack of any broodiness is a bonus because it makes it all the easier not to regret the positive decision I made many years ago that I do not wish to be a parent.
