Pro-Life Synthetic Rage

I don't believe it is helpful to question other people's beliefs or motives, but after watching both Republican debates, I have to wonder if some of the pro-life stances are not just synthetic rage.

I think it is reasonable to question a candidate's reasoning and judgement. For example, any candidate who doesn't believe in evolution doesn't have the scientific background, judgement or common sense to be president.

Do the candidates who so intensely state life begins at conception really believe that? They must believe that conception occurs with the union of sperm and ovum and not with implantation otherwise they wouldn't consider cells in a petri dish to be a human "child" (now there is a way to ratchet up the the rhetoric).

With a definition that life begins with the union of sperm and ovum, aren't many treatments for infertility, which routinely create embryos that are later discarded, forms of murder?

Aren't many forms of female contraception, which prevent implantation in the uterus of a fertilized egg, also murder?

None of the Republican candidates turned their synthetic rage toward couples using in vitro fertilisation or toward women on the pill. I guess political moral outrage has its limits.

Rabid pro-life positions fire up many in the Republican base, but I would expect a serious candidate for the presidency to have a better understanding of this difficult issue. Give Rudy Giuliani credit. He has had to face the issue with logic and reason instead of hyperbole. Maybe he can articulate a position that will add substance to the debate rather than just fire.
