I don't really care about the politics of it. It doesn't really effect my life. I'm slightly supporting abortion because I'm concerned about the quality of life of the mother and father. However I am saying that the ethical logic is sound. What's the difference between killing a man versus killing the man while he's still a baby inside his mother? That being said there are scenarios where the above logic does get seemingly absurd. At what point is it considered murder? If I use a condom, I'm basically aborting sperm, because anyone of those little guys can become a full blown human being. Is that murder? Note that I used the word "seemingly" it seems absurd but the question is worth considering as much as abortion itself. Is using a condom murder? Is abortion murder? I don't know. But the ethical paradox is real.
