The reason "is a defiler" "uses magic" Or "is a criminal" are not the same as has a Red or Gold aura is that these last two are absolutes within the realm of CF. Every player and NPC should have an awareness of inherent alignments in such a world where priest and magic make such information readily available. Focusing on something other then alignment as a label to allow unfettered killing does not change the nature of the person you are killing. You can believe that magic is evil, but that does not change the fact that the storm giant village should have awareness that the elf mage at heart is a good being. And while he may agree with the duergar warriors views on magic being all buddy buddy at all times would seems counter to the nature of the beings and their inherent alignments.

The primary idea that comes to mind when I read these posts is that most people are espousing the idea that the ends justify the means, namely that a good character who has certain beliefs can kill other good characters with the opposite belief. The problem with this type of philopsophy is that it is inherently selfish and ignorant of the fact that in CF characters have defined alignments that are not questionable.

And as I stated in another post, playing such a character is fine, just realize you are not good, but are neutral or evil.
