On the surface it is a controversial post, and probably should be. But that is only if people think that today's outcomes will amount to the same exact results, as they did for the Nazis. The Nazi genocides were a product of a particular time and place, quite far off from modern realities.
Not putting human life at the center of everything, does not inevitably lead to the same amount of suffering and atrocities that it may have led to in the times of Hitler and the Nazis. Today, we have means at our disposal with which we can prevent children with serious defects from being born, before they reach the stage of developed human life.
It is not Hitler who is ordering people to abort their children. It is the people themselves who are choosing to do so, by their own will. And there are no gas chambers or concentration camps being utilized to accomplish the feat, either. The shame of Nazi atrocities, does not really resonate with people who partake in the modern version of "eugenics", because scientific progress in these areas has basically reduced the element of human suffering, down to nothing.
It's not a matter of whether we should or should not. It's happening, whether we like to admit it or not.

Are Icelandic people Nazis? Maybe or maybe not. But they've accomplished something even Hitler couldn't do. And I reckon that they won't be the only ones to do it, eventually.
I actually advocate for limitations on abortions, etc. to increase population growth in my own country, which is suffering from an aging population, and a huge decrease of birth rates. But my arguments have nothing to do with the shame game that the Pope is trying to play, which is bound to end in failure due to a complete misunderstanding of the respective circumstances. For me, it's just about basic maintenance of a society for the long-term.
For some societies, abortions are a dire necessity.
