Someone who, despite living in a world where magic is part of everyday life, considers magic to be "unnatural" and something you should avoid at all costs. The person who dislikes magic may be a practitioner of Arbitrary Skepticism. Compare Flat Earth Atheist. Both are about supernatural settings where one character is set apart by preferring the mundane, whether by choice or ignorance - but it is still much closer related to Nay Theist: Both Flat Earth Atheist and Nay Theist refuse to believe/worship, while a Magic Hater just thinks it is bad, evil or dangerous.
