That is not the definition of relative. Stats are an absolute scale. All Str 15 characters are equally strong, regardless of anything else. That something can be stronger or weaker is not a relative scale.
RAW is meaningless. It's up to every DM to interpret the rules for their own game. Some rules are meaningless regardless of the game. Morality and alignment go hand in hand and both are quite relative.
Now, I will agree that it is up to every DM to interpret the rules for their own game. I agree with that 100%. However, when discussing the game, with other gamers, we cannot use our own games as the baseline. I could be lying about my game, I could be arguing in bad faith. I could be mistaken. There are any number of things that could cloud the issue.
When discussing the game of D&D, not Hussar's D&D, or Aria's D&D or Diaglo's D&D (the one true game), we can only go by the text. We can discuss different interpretations of the text, but, we cannot ignore the text and substitute our own definitions.
Alignment in 2e was relative. 3e is not. It is very concrete. Under no circumstance is an angel an Evil outsider (barring, of course, changing the creature in question). Animate Dead is an evil spell. That has specific game mechanical meaning. Good clerics cannot cast it, for example. Also note that zombies are "Always NE". By creating undead, you are actually creating evil creatures.
Your campaign is fine. If you want to play that way, more power to you. But, you are deviating from the RAW, and, as such, you're campaign cannot be used as a baseline for discussing the game.
