Why do these scientists think we should take them seriously when they reveal their hypocrisy in their own statements. If it's a sin, then they accept an objective moral standard outside themselves such as God. But if they did accept God then they would value life as a creation in the image of God. So these scientists are hypocrites from the very start.
The scientist's concerns about the "quality" of our children is just a code phrase for genetic selections. the problem is, whose genetic ideal is to be followed? Clearly Hitler lead the way in their mindset with the pure Aryan race and his efforts to pay attention to the "quality" of our children. These scientists are nothing more than latter day Nazis at heart...but would rather couch their bigotry as concern.
