So? You honestly believe that the 'abortion is murder' claim is someday going to be constitutionally established?
Try to keep up.
It ALREADY is established in more ways than one.
The problem is that those same laws (for now) make and exception for women who choose to have one "legally."
However, if YOU attack a woman and kill her child (abort it) "CRIMINALLY. . . "
YOU will be charged with MURDER.
So, for as long as even an illegal abortion is recognized as a murder.... The comment "abortion is murder" is in fact true. It doesn't have to mean that ALL abortions are murder. If even one abortion is a murder, the premise is established.
Exceptions are not the rule. That's why they are called "exceptions."
