It's not a straw man at all and that's what you can't grasp. Either one classifies a fetus as a human being with ALL the rights and privileges of a human being or they don't classify it as a human being. There is no 1/2 way measure. There is no killing an innocent human being because of the defective body of another human being (problem pregnancy). There is no killing a human being even if genetic testing shows the fetus is so malformed or severely damaged it will never leave an institution and will suffer painful medical procedures and be left alone rather than have it's mother to hold and feed it.
Try and wrap your mind around the reality and stop the nonsense of "well, this case is different" or "in that case the mother's health comes first" or some other exception.
There are no exceptions when it comes to human beings. Either fetuses, once classified as human beings, will have the same rights as everyone else or we go back on the path society has taken too many times before.
What are you having a problem with? Have you ever read a history book? Once exceptions are made for a group of human beings, in this case fetuses, all hell breaks loose.
For the love of God educate yourself. If you can't understand the imminent danger in what you propose, classifying fetuses as human beings while suggesting the defective mother's life ALWAYS comes first, you set a precedent. A very dangerous precedent that has been used concerning other human beings down through history. Nothing good ever came of it. In fact, it always turned out bad. Very bad.
I suggest you start by a visit to a hospital for sick children. Go there. Soak up the cries and screams. Immerse yourself in the suffering brought on by those who didn't believe in abortion.
You have no idea what you're talking about or proposing or the inevitable consequences. Talk about a sick fuck.
