I don't get the hate specifically about the Moon sisters, I mean everything about the way they are is explained perfectly in the context, and while I don't really care about them either I think all the ranting about them is obnoxious. Their attitude? They're literally brainwashed by Lunar Capital propaganda, and in fact if their story is anything to go by they're actually less snobby and obnoxious compared to the Lunarian elites(there's also the fact that "impurity" has an actual physical effect in Touhou, and it's lethal to the Moon people. Like, avoiding someone or something infected with Ebola or smth isn't really a bad thing now is it?). Their power? You can't be the defender of a powerful and legendary kingdom without being OP to some degree. Them being unable to be featured in a game due to being powerful? BS, Hecatia is literally a boss in LoLK, the reason they can't be portrayed is because Touhou is a low-res bullet hell game, and the Moon sisters(Yorihime in particular) are like RPG characters that would require entire pages worth to explaining all their abilities and what they do. Imagine trying to render all of that crap in a game format like Touhou of all things...it might literally crash it. I simply can't find fault in them to hold against them, and they are exactly the way ZUN wants them to be. If anything the subject of hate should be the unknown Lunar elites instead. They also aren't infallible either, Yorihime fell to a trap, and got knocked out ffs. If an enemy of the Moon like Junko happened to be in the vicinity when that happened, then it would've been lights out for good.
