Your question looks very much like a trap to me. Sort of like asking "when did you last beat your wife"?
Respectfully disagreeing with an opposite opinion on say, how much should be allocated to NASA this year for research is one thing. But respecting a man who declares that legally slaughtering babies in the womb is a constitutional right is quite another. This issue makes Rino Giuliani a dispicable man for another reason as well. He recently tried to sell to the American people the proposition that he'd nominate pro-life SCOTUS justices like Scalia and Thomas. Then he comes right out and declares that abortion is a Consitutional right that needs to be protected. He's a scumbag.
Nice intellect there cowboy.
