1) Abortion, cloning, etc. will be seen as bad things and will be increasingly rejected by our society.
OR
2) People will say 'The Nazis were actually right about a lot of this stuff. maybe we should give their philosophy a second chance'.
If I had to guess, I think Option 2 is more likely. Sigh.
Option 2 is what the culture of death is trying now. They get very testy when their connection to Nazism is brought up, and try to reject the comparison out of hand.
It makes more sense for us to expose it for what it is and hopefully the minds and hearts of society will change.
