Abortion, Torture, and the Slippery Slope

Mark Shea has an interesting essay comparing the artificial birth control = abortion = infanticide slippery slope to the recent calls from some conservative Catholics to open the debate over the acceptability of certain non-lethal forms of torture in the war against terrorism:

How far down the slope will conservative Catholics be willing to slide before they recognize that they too can be lulled into making excuses for intrinsic evil and mortal sin? The next few years will tell us. My prayer is that the Right will learn from the mistakes of the Left and not repeat its sins of justifying the commission of evil for some greater benefit.
