Leaf hate is a manufactured psyop by her opponents and Cirno. In the BS fandom she's rightfully seen as the main heroine (#1 on the popularity polls by a large margin) with zero dedicated haters, and Leafscholars are seen as paragons of good taste.
She's also much better than the dog-fucking whore, the shitty Alice meme, the autism cat, the bad-at-chess alcoholic deadbeat father (female), the necro-whore... Vote Leaf, the true heroine!
