Why does anyone care what other people do? Your life so sad that you have to worry about what others do?
Yeah! Why should any of us care if some other person is drugging his dates to sell them into prostitution overseas?
Why should any of us care if our neighbor is kidnapping kids off the street to rape them in the privacy of his own basement, and then cooking them for dinner?
1 because he is KIDNAPPING
someone else's kids
2 because he is raping them
3 because he is killing them and eating them for dinner
in each one of your scenarios, there is a born person who is being harmed by another person with no attachment to them.
SOME people believe that an unborn child in its earliest stage does not have the same value as a child that has been born and taken its first breath.
Others believe that from the second of conception, the unborn child has the equal worth under the law as the born child.
Others believe that this takes place upon pregnancy, when the fertilized egg is attached to the uterine wall and begins rapidly multiplying because many fertilized eggs end up being flushed and not attaching to the uterus.
And others believe the fetus has no worth until it is born.
Some others believe the fertilized egg as no worth until the woman makes it through the first month of pregnancy, because many spontaneous natural abortions occur at that time when the body rejects most embryos that are damaged...
