Of course the OP has "witch" in her username

Medieval witches would do shit like kidnap young girls and harvest their menstrual discharge to try and create youth potions to smear on their skin and keep it looking young. The stem cells in young children's blood has an anti-aging effect, which is why in the past noble women would do depraved shit like bathe in the blood of young maidens. Witches would sometimes drink the potions instead, or even go so far as to kill the children and cook and eat their corpses. The only reason witches are "cool" is because they've been whitewashed, just like pirates and vampires. Not to mention the whole thing with licking cat anuses to infect themselves with parasites to give themselves "magic powers". Or voodoo witches who would drug people into a near-comatose state to make them gullible so that they could gaslight them into becoming their slaves (origin of zombies btw).

Witchcraft is the art and science of using various techniques and technologies (primarily applied psychology & biochemistry) to gain power over others (through physical beauty, sex, brainwashing/indoctrination, drugging/poisoning, etc.) Shit's absolutely fucked up.

Incidentally, the concept of succubi (in the sense of being possessed by a succubus) stems from female rapists, since unlike with men, the thought of a woman committing rape was so unthinkable that they went as far as to chalk it up to supernatural influence. Also whitewashed, obviously.
