Just because you feel a certain way about something doesn't automatically mean that I should as well.
Of course. While I don't fully agree with them, there is a tiny grain of truth still in what Dave and nctnico are saying - many who "do not want to have kids" actually change their minds, some unfortunately too late, some still in time, and it is
way more common to change your mind that way (no kids -> yes kids) than the other way around, and this bias in direction is pretty interesting, I think it shows we humans have built-in "yes kids" attitude, which, if you think about it, makes total sense biologically. So in most cases, the biologically "obvious" is true.
So chances are actually pretty high that many "no kids to me" people are not actually that way "deep inside". Maybe they think that way because surrounding attitudes are affecting them? Maybe they have some personal reasons which they could work with instead of just accepting as something unchanging? That's why people like Dave and nctnico try to "convert" you. They are saying, "You will like it, even if you don't believe it now. Don't waste time because it is easier the earlier you do it."
I'm not trying to convert anyone, however. But I'm seeing their point. It makes logically a lot more sense than trying to convert you to like broccoli, or some certain deity they happen to believe in.
Then again I'm sure there are many who truly, genuinely, will never want kids and will be genuinely happier with that decision for their whole lives. But the group of those unhappy with that decision is, I believe, a lot larger than the group of people unhappy with the decision to have kids.
Especially women who unfortunately have this biological clock ticking faster than men. With our current standard (pushed by media) that we must party until 25yo, then we need to start thinking about taking studying seriously, then after graduating at 30yo we need to start thinking about "building a career", then at 35yo we should start thinking about finding the "final" partner, then at 40yo we should start about thinking actually settling down with them and consider having kids.... it's too late.
Me and my partner, we wasted time really for no reason. Now me 41yo and the kid is 3yo. I would not undo the kid (of course, it is quite rare to feel that way), but if I could change something, we should have done it at very least 5 years earlier, even better 10 years. So I'm also one of those for whom it was the right thing to do but should have believed in that earlier. But oh well, one very healthy kid, I have nothing to complain really.
