This story really frustrates me.

For once, I want to see a powerful Witch who doesn't give a fuck about discriminatory bigots and is not afraid to use her power to punish them.

Actually, there are two Webtoon/Webcomic Witches that are unapologetic badass bitches:
Dolly (Cowboys & Dragons - A Fantasy Western) + Lunarella Nocturne (High Class Homos)
