Both Krauthammer and Thomas invoke Nazis while discussing Obama's stem cell order
From Charles Krauthammer's March 13 Washington Post column, titled "Obama's 'Science' Fiction ":
I am not religious. I do not believe that personhood is conferred upon conception. But I also do not believe that a human embryo is the moral equivalent of a hangnail and deserves no more respect than an appendix. Moreover, given the protean power of embryonic manipulation, the temptation it presents to science and the well-recorded human propensity for evil even in the pursuit of good, lines must be drawn. I suggested the bright line prohibiting the deliberate creation of human embryos solely for the instrumental purpose of research -- a clear violation of the categorical imperative not to make a human life (even if only a potential human life) a means rather than an end.
On this, Obama has nothing to say. He leaves it entirely to the scientists. This is more than moral abdication. It is acquiescence to the mystique of "science" and its inherent moral benevolence. How anyone as sophisticated as Obama can believe this within living memory of Mengele and Tuskegee and the fake  (and coercive) South Korean stem cell research is hard to fathom.
From Cal Thomas' March 13 Washington Times column, titled "Journey to Destruction ":
What will constrain science? The president says it will be up to the National Institutes of Health to come up with "guidelines" for the use of embryonic stem cells. He specifically came out against creating embryos for the purpose of human cloning. But the question is this, if there are to be no moral, ethical or religious restraints on the initial experiments, why should anyone expect them to be invoked later? One can only be a virgin once. After a moral or ethical line has been erased, it is nearly impossible to redraw it.
At the extreme, unrestrained science has the capacity to produce a Josef Mengele. The Third Reich "scientist" and doctor was given the green light to do whatever he wished with Jews, twins, the physically deformed, the mentally challenged - all in the name of "science" and progress. We are repulsed by the horrors he created in his "scientific" laboratory, to which many of the German people turned a blind eye, mostly because they had been conditioned to do so by nonstop propaganda, which convinced them that some lives were less valuable than others.
We have been warned by history, in novels like Aldous Huxley's "Brave New World" and on TV news, of what can happen when government operates outside a moral code established to protect us from its penchant to be excessive. Unfortunately, government in recent years has sometimes engaged in a type of moral freelancing, embracing a mushy morality in order to serve purposes that are sometimes immoral.
Removing restraints on stem cell research is another step on a journey leading us to a distant somewhere. Does anyone know the destination? Do enough people care that it might just be leading us not only to the destruction of more pre-born human life, but also ultimately to our own end?
