As you posted, you are just ONE of those people; hardly enough on which to base a balanced opinion. If you're going to study historical foster children, again, also study those who didn't overcome adversity. The problem you'll likely encounter is that there not as much recorded history; certainly not likely to be the sort of history that's promoted and read about in our history text books.
"You can not marginalize people based how you perceive life should be for them." Marginalize isn't what I'm doing. What I'd be doing through abortion is saving babies, children, adolescents, adults from a hellish life.
I still strongly maintain that the choice to carry a fetus to birth ought to be a woman's choice.
