Personally I hope to have children and don't 100% agree with the notion of being childfree.
I understand if people don't want to have kids because they think they're not good parents or don't have the financial backing to support a child. But to some extent, I don't agree with the notion of having to abort a child because a couple wants to be childfree.
If the child was conceived, then it becomes the parents responsibility to carry it and take care of it as they can. If this means foster care, or passing it to relatives...then so be it, but once conceived, I personally think that the child should be given a chance to survive. (this is sounding anti-abortionist so i'm gonna stop that there rather than side track this discussion).
Otherwise, if you have legit enough reasons not to have a kid....then go ahead, use contraceptives, or whatever you want, it's ultimately your choice. Personally I love kids and would love to have one, or some. But I also think that parenthood isn't something that you KNOW you're not fit for...until you have a kid of your own. Of course, if you don't want to risk it...then again...that's totally your own choice. I'm not out to say that, every woman was put on earth to have kids....cuz well, that's just simply not true.
You see kids in foster homes having a hard time, or kids born into broken families with dead beat parents or little "brats" whom you shake your head and wonder what the parents teach them (IF they teach them anything useful at all). True, but these are all "what if"s...in the end...you just WON'T know until the time comes. Unfit parents are one thing, not giving kids a chance is another. Bad parents doesn't mean 100% bad kids...even if the odds are against it, who can say with absolute certainty that any kid born at any second will turn out good...or bad?
I can't say I enjoy all kids...some can be quite..."taxing" at time to say the least....but yeah, that's just my view point of it all. Last point, no parent is the perfect parent...no kid is the perfect kid...that's not the point of parenthood...just keep that in mind
