The Gerudo are forced into a unique situation by their inability to produce males; they must actively seek out Hylian males to mate with or else their tribe dies. There is no indication here that the Gerudo or the Hylians are part of a culture of casual inter-breeding for reasons other than to keep the Gerudo tribe alive. There is no indication that the Gerudo maintain relationships with Hylians before or after their babies are born. There is no indication that the Gerudo babies form any part of Hylian society, which would allow them to affect the Hylian population. And most importantly, there is no indication that any of these points occur for other races in Hyrule.
In short, you take the simple fact that Gerudo rely on inter-breeding to keep their tribe alive, and you build on top of that with a lot of baseless assumptions to suit your theory. Unless you have anything more concrete to justify your theory, then I have nothing more to say on the subject.
None of that, whatsoever, is a smidge of evidence against the possibility of other races interbreeding for any other reason. And given the issue with LTTP, and the fact that your beloved "Magical symbolism" wasn't yet constructed in the series, implies that interbreeding is the culprit. What part of "thin blood" is so hard? It's not even like the issue where the Sages, where the kanji for blood has alternative meanings.
So you are arguing that because stagnation is itself a form of change, stagnation cannot be visibly represented by the decline of magic? How can be the principles of order and stagnation be upheld if stagnation cannot by definition be seen to occur?
No, the decline of magic is change, so it can't be stagnation.
I never provided any specific definitions of spirits and magic, but I am stating that spirits and magic exist for people to explain the nature of our existence, and that they thus operate beyond physical laws. The fact that everything physical in the Zelda universe has a magical essence demonstrates this clearly.
Saying things like "Magic is a connection to the divine" is by no means universal, even in the context of the series, is what I meant.
It's called context. Majora's Mask takes place in another dimension, in which the characters are given different identities than in Hyrule. The Gerudo are no longer thieves, but pirates. The Deku now have a royal family, the Zoras all enjoy a modern rock music group. I don't think that what applies in Termina applies to Hyrule because Termina is not meant to be a reflection of Hyrule.
So Termina doesn't apply to your Magical Symbolism stuff? If you're going to make big sweeping observations about the series multiverse, you can't just exclude a world because it doesn't fit cozy.
Could you elaborate please? Metaphysics is a form of philosophy, not science, and I cannot find any defined metaphysical laws on the internet that relate to this debate.
Metaphysical law, as in laws that work outside physics and/or OVER physics. An example would be "all souls must be reincarnated based on their karma" or something.
