Life and the worth of it

"The child will be born with a disability and their life will be harder then normal. Wouldn't it just be better to abort the fetus? Wouldn't it be kinder to make sure that this baby isn't born with any defects by aborting?" This is an argument often given by abortion advocates in America. Does this argument stand? These pro-choicers would be right in part of their argument, that the child will have a harder-then-normal life. But their conclusion doesn't follow at all.

My family has had a large amount of experience with mentally-disabled folks, and a family that's close to ours has a down-syndrome daughter. I know that being mentally disabled is hard. The daughter of our friends turns 14 this year, but in my minds she is about 8 or 9. She struggles with reading and other mental tasks. I'm not envious of her position, but her life IS worth living. She has set-backs. That's undeniable. But she wouldn't want to be aborted. Every moment she gets to see a brilliant blue sky, every moment that she gets to enjoy playing with her sisters, every moment she takes delight in giving people hugs, every moment she performs ballet, every game where she gets to cheer on her brothers, every moment where she can take joy in the fact that Christ is her savior, every moment she knows that she is loved by her family, every moment where she can take joy, deep or shallow, important or trivial in anything is a moment that says, "Life is worth living."
