The problem with legalized abortion is that there are certain individuals in the world with selfish ideas of right and wrong and they want to make sure that everyone else supports those ideas regardless of the extent to which it discards the rights of others.
Laws defining cruelty to animals restrict activities of some people who have a different moral outlook than PETA. However, those laws are still enforced and people are required to abide by them; to follow that restrictive moral code.
The position of anti-abortionists is that the fetus is a human person. That person does not deserve to die because someone feels "put out" by their existence. Certainly there are times when one person's rights must be subjugated to the rights of another, but is "inconvenience" a valid reason? This is a position that is not likely to change easily.
A birthed person has definite rights and a fetus does not. That is a matter of law, not an indication of what is inherent or what is not. A change in the law could change the rights of individuals.
Being able to express your desires, will and needs is not a precursor to having rights, else infants and invalids would have none.
We should take procreation seriously and have children when we choose to do so. However, I see this as an argument to support widespread application of contraception education and availability, not abortion.
Anti-abortion activists cite two issues: The high numbers of abortions that are occurring and the fact that abortion is killing a child. In the face of the high odds against having abortion completely criminalized, they have opted for legislation that could lower the numbers of abortions. To this end they have adopted means that are manipulative and even duplicitous. If they are willing to skirt and even cross a Biblically established moral line, by lying to control women's behaviors, then why not skirt another Biblically established moral line by supporting something that MAY make sinning more likely but minimizes abortions?
It is this very selective breaking of their own moral code that throws into the question the truth of the claims by their leaders that their only goal is to stop the killing of babies.
Is abortion the killing of a "person"? I believe that in the gestation of a human, some point is reached where that clump of cells becomes a person. That fuzzy line is difficult to place, but it is unimportant. The key not making abortion illegal, but instead to avoid getting pregnant in the first place. Whatever policies or education that can make that happen should be supported by both sides of this debate.
