I largely agree with Mal

As I pointed out on similar threadon WOTC forums, in many D&D worlds, Evil, Good, Law and Chaos are REAL forces.
Try arguing with a Balor about that

Moral Relativism simply doesn't fly in most D&D settings. It's like saying "Hot" and "cold" don't exist.
I liked Maruts being absolute Lawful enforcers of universal laws. Why not? It's
fantasy, not "Papers and Paychecks", I like playing heroes, not laywers, for goodness sake
So, far as I'm concerned, the 9 alignments still exist.
Oh, one point though, Mal:
Why would a drow NOT have Proteciton From Evil, hm? Who do they fight the most? Certainly not paladins!
No, they fight other drow and eivl creatures most of the time, thus, they damn well better have Protection From Evil!
Just that since most drow cannot have Good as as their Domain, they can't get the
bonus protection spells for that
domain, is all.
So in my games, the one spell you can bet many evil creatures have is
Protection From Fellow Backstabbing Slimeballs
