After Voldemort is defeated and global wizard equality is achieved, the influx of half-breeds and less capable wizards into Hogwarts and other magical schools grows dramatically. Criticism of this change is met with accusations of bigotry and calls of “you are starting to sound a lot like You Know Who with that talk!”. This continues with miscegenation becoming all the rage for the next hundred years.

By the year 2100, magical blood lines have become so diluted that very few people can still actually use magic. Magical creatures find that they cannot communicate with students at school, wands begin to refuse ownership, and tensions rise as “pure” students begin to unite. The fear of a return of the Dark Days is still strong, and those critics who raise concerns over the decline in quality and use of magic are labelled “bigots” for their anti-muggleborn views.

In more progressive circles, prominent “intellectual” wizards begin to suggest that magic doesn’t really exist – not objectively, anyway. Magic is merely a social construct and witchcraft and wizardry can manifest itself in many forms, most of which don’t involve the use of magic at all. This is met with great approval by the majority of the community, though there is still discontent among those who continue to actually use magic correctly.

To combat the growing discontent, the Ministry for Magic decrees that “flagrant displays of magic” are now illegal on school grounds, as this can result in prejudice and feelings of unwelcomeness for muggleborn witches and wizards who are utterly incapable of casting spells (even those who manage to keep wands). The school removes it’s “applied magic” curriculum and replaces it with “Justice-Oriented Magic” and “Muggle Studies”, which focus on present-day social issues and the various expressions of “Alternative Magic” that are popular at the time, such as Ouija boards, tarot cards, and divination of palms and tea-leaves.
