I hate to say this because it seems so un-Christian, but 2004 has been full of unexpected gifts. The demise of this virulent, anti-America, hate-filled and bitterly unhappy woman is just one more.
Apparently, you don't hate to say it enough not to say it.
And yes, it probably is "un-Christian" to consider the death of someone you've decided is "unhappy" (among other things) to be a "gift."
The psalmist provides you with ample precedent. Anger is not a sin. Staying angry, hating and enjoying hating, is most definitely sinful.
I do, I will admit, regret the fact that Ms. Sontag's eternal sojourn in hell will not repair all of the harm she and her ilk have wrought upon Western culture.
