The point is that the law would never have been passed if it wasn't for the political gains involved.
this isn't about the pregnent woman making a choice not to carry the potential child to full term.
Actually it is. The difference between your nose-punching example is that there is not a large ideological movement dedicated to recognize noses as human beings.
Beet,
There are several issues here.
First, who should decide on major matters of public policy? Lets be honest, the Supreme Court in Roe and Doe legislated from the bench. An 'emenation' from a 'penumbra'? Absurd!
Second, the majority opinion in this country is that abortion should be permissible in some, but not all, circumstances. The pro-abortion forces are unwilling to accept any restrictions!
Third, if abortion on demand can be written into the Constitution by a group of overzealous judges, then the Constitution becomes a blank check for the judiciary. This scares the hell out of me.
