I have you agree with you KM, I have read the Detect Evil description many times, and I don't see anywhere it states it would detect a character with a Neutral Evil alignment as a "evil creature". The description in the PHB is way too vague to make a case for or against this, so I just houserule it and say it ONLY detects creatures with an evil subtype (demons, devils, undead, some elementals and faeries), and the rare cleric of an evil deity. I think the ability is more interesting this way, and much less prone to player abuse. I don't understand the stong resistance some people seem to have to interpreting things as you see fit or rewriting things for your game- it is YOUR game afterall.
This is true. It is all open to personal interpretation. However, I would find it silly that a Detect Evil doesn't work against an Evil-aligned Human
if Protection from Evil offered any protection against the same human.
By extension, you cannot use Protection from Good on your BBEG to provide AC and Save bonuses against the majority of the people in your PC's parties.
If Detect Evil/Detect Good does not offer information on alignment, then Protection spells should not offer any bonuses based on alignment. Nor should the Dispel spells offer protective value to recipients. All of these spells dictate that they work against Evil/Good/Lawful/Chaotic creatures. If having the appropriate alignment is not enough to qualify, it should be that way unilaterally.
Holy Smite and a Paladin's Smite Evil (And a Blackguard's Smite Good) use the same wording as well. Holy Word specifies that it works against non-good creatures. It isn't the same wording, but it is similar. Once again, a unilateral application should occur to maintain consistency. Otherwise, your players are going to want to know why a human with an evil alignment is not evil for Detect Evil, but is evil under other circumstances.
Personally, I think my player's would hate that. So, in my games, having the appropriate alignment pings you as that type of creature. Otherwise, I am shutting down the effects of several spells because one spell is inconvenient to me. Of course, you don't need to maintain the same internal consistency in your campaign, but I think it bears mentioning that there is a grouping of spells that depends on the "evil creature" mechanic and you should keep that in mind for your rulings for your game.
