No one is "defin[ing] when life begins. "
All they're doing is defining what is legal and illegal wrt abortion.
A verdict of "justifiable homicide" hardly means that the victim wasn't alive; it just means that no penalty attaches to killing him (because he was attacking you, or threatened to kill your neighbor, ...).
I don't like Roe v Wade, criminal statutes should be up to the states unless they're in conflict with the Federal Constitution or Federal statutes.
"Unelected" or not, the Justices who ruled on RvW were duly appointed. I don't think poor decisions constitute "bad behavior" as grounds for removal. I have been in states where judges are elected, and I didn't like it at all; I think the Fed. Const. got that provision right.
That's all very nice but the fact remains that "the peopele" never contemplated giving unelected federal judges the power to make law from the bench. There should not be any controversy about that on a conservative website. That there is causes me considerable angst but I always manage to get over it.
