None whatsoever. Just disagreement over whether or not judges are allowed to make stuff up.
That's not the ***ing disagreement and you know it. There is a reasonable Constitutional argument extrapolated from various ammendments for a "right to privacy" that protected abortion.
Read some Constitutional literature for Christ's sake. There have been debates going on ever since Griswold v. Connecticut about privacy in the Constitution. Lots of extremely smart people on both sides disagree strongly about which way the Constitution points, not simply whether it's good to make stuff up or not.
Should is a fun word. However, ammendments often can be passed to fix disagreements, as I pointed out earlier. War isn't a great option to solve the abortion question, but maybe that's just me.
