The protection from alignment spell exists in the game so yeah, why shouldn't we be able see or choose what our alignment is? Maybe it just acts as a general purpose protection spell now but it's suggesting that there are still alignments at any rate..

I do feel that in video game world being able to designate your alignment helps define your character better.. even if it's just a tag that has no bearing on the game play. It's the little things that make you feel like you are creating your own unique character.
