The Swastika was, at one time, a benevolent power symbol scrolled on temples around the world, owls were great power animals and keepers of wisdom, even the devil horns hand sign is an adukterated mudra or hand position used to channel or focus energy. They want the wrong symbols used in the wrong places to disrupt the magic that we are, and harvest that joyful energy as loosh.
