"Would you ever consider adoption?"

I was reading one of many survey bulletins on myspace when I stumbled upon someones answer to that question.
They Answered simply "no", It made me go into deep thought for awhile. I was trying to figure out why they would answer "no".

Don't assume I believe the right answer is 'yes', I'm just thinking why they picked 'no'.
Maybe they want kids of their 'own'? (Whatever that's suppose to mean). That seems plausible I guess. Most people want kids, especially blood related kids.

Excuse me if I'm out of line but doesn't that seem a little selfish? I mean...you would never consider option? That's what the question is after all, it asked would you ever 'consider' adoption. It didn't ask "would you ever adopt?"
It seems really selfish to bring another child into the world when there's so many children waiting for a loving home. Especially people who have hereditary issues and/or problems that they'd pass on to their offspring.

Your not gonna adopt a healthy child because you wanna have a child with AIDs? Or a child with many other problems? Excuse me but your future retard baby is not wanted when there's others who need a place to live. I mean its not like abortion, the child you want isn't even a life yet. I just don't know peoples problem with adoption. Maybe when your older, like 25-35, you have an urge to have a kid and that's what happens to people, Ive heard about that a few times and it worries me a bit to be honest.

Well if you did assume when I told you not to, the right answer is 'yes' I believe.
Personally, I don't ever want kids, for personal reasons I don't feel like discussing. I'm not against getting married or anything like that, but I'm very open to adoption and along with my personal anti-offspring reasons, Adoption seems like the clear choice if I ever want kids. If I do have children when I'm older I hope I go that route.

I never did ask them why they choose that answer...

It just seems odd to not even consider it, that's what I think anyway. There's a lot of potential for discussion on this subject and Id love to hear others opinions.
