I was pretty impressed too that it didn't dissolve into hysterical name calling too, because when I opened the OP I did assume it would get ugly based on how other boards go.
I agree with pp that being older we're probably better at accepting others opinions. I'm not going to take as some personal affront if someone disagrees with me.
I also think we're old enough to know that life is not black and white, and to realise that no matter what your stance on termination if you're actually faced with a baby with medical issues then it's an incredible stressful and difficult thing to work through. Regardless of the decision you would make, or the possibilities you would consider, no one skips off into the sunset singing, "tra la la"
