My perspective stems from thinking about the individual mother.
Are they psychologically mature enough to raise a child? Mothers - young mothers in particular - may have to sacrifice their social life, job and even chance of higher education to have a child. Unless they have a financially secure AND supportive family/spouse, raising a kid is going to be one hell of a challenge. There's always the possibility that the young mother gets kicked out of her house for being pregnant, and gets dumped by her lame-ass boyfriend 6 months into pregnancy. What then? What kind of growing environment is that?!?!
Yes, some mothers love their children enough to make things work... but single parenthood, or even just regular parenthood is expensive and emotionally taxing. I actually have full respect for those people who recognise that they're not ready for that yet (most girls my age are at their 'peak' for bearing children, but are we emotionally or financially ready? hell no!). I don't want to screw myself over emotionally, and in turn raise up a child that's equally screwed up due to an unstable living environment.
I firmly believe that anyone offering counselling to someone considering abortion should be able to advise them to do what is best for them, not "following the beliefs of a biased institution" (ie religious organisations who often show horrible "abortion footage" -"foetus corpses" and so on, intended to shock the mother-to-be into refusing abortion). Like seriously. What kind of counselling is "If you abort this child, you are killing a life?" That's guilt tripping in my book. That is NOT counsel, that is "persuasion".
