You really just don't understand. If the seed is inert, then Natsu isn't physically a demon. The seed isn't working. The dragon seed isn't a dragon, therefore the demon seed isn't a demon. When active and taking root, it is something that changes the user to that species. When not active, it's just some growth somewhere that does nothing, that nobody can detect. Maybe go re-read the last bunch of chapters and then talk to me, because a 12 year old could grasp this.
