Moe is a feeling. Though I do think it means more than that. And more than a character you want to protect, too.
Yandere and Yangire characters are called moe a lot. But I don't think they're characterized to be protect.
I do think that moe is a very broad word. But I do think it means something. Moe is a cultural trend in anime, and it has some good sides and bad sides. The anime industry is cuter and more feminine, now. I think.
Moe is a bunch of things together. Like a trend. Not all of them are bad.
Moe doesn't just mean loli. While I don't agree with what everyone here is saying about loli, I kind of hope we don't talk about that too much here, .. I wouldn't like this to end up like the Next Door thread.
Loli does have some things to do with moe. But moe has to do with a lot of things. From what I understand, moe came from the shoujo and bishoujo culture. Especially magical girl anime and visual novels. Bishoujo visual novels are mostly for straight boys, but that doesn't mean everything about them or moe is bad.
Moe anime is a lot less violent a lot of times. A lot of anime that wasn't moe was also very violent and about male characters rather than female characters. And a lot of moe anime isn't just for men and boys. It's for people of all ages and all genders. Having female characters that everyone can like and relate to. And even if a show was hoped for one audience, like men, doesn't mean it can't appeal to others.
My Little Pony was made for little girls. But plenty of boys and adult men and women like it. It's an all ages and all genders show. Just like many moe anime are. Most of my friends are women, I don't actually have many friends that are men. And almost all of them are fans of moe anime. One of my best friends is a lesbian who loves Lucky Star, Yuru Yuri, Umineko no Naku Koro ni, and Puella Magi Madoka Magica. She doesn't like My Little Pony, though, which I wish she did. :< She made me watch Madoka Magica, which I didn't like because it was so depressing.
Anyway.. um... what I'm saying is that nice things can be for all genders. Moe isn't just for men or boys.
Moe are... well... they're not just endearing things, I guess. Though they could be. I guess it's kind of like the word anime. Anime means all animation. But it also means Japanese animation for many people. With moe, it means things like endearing personality traits and physical traits. But it also means cute traits that have been popular in in otaku culture, like Magical Girl anime and Bishoujo visual novels.
So, I guess, when you're talking about moe, you're talking about otaku culture and a little bit fujoshi culture. And what they like. Otaku and fujoshi like different things, but it is a culture. And all cultures have good and bad things. So when people say that they don't like moe, and that all moe is bad, it's like they're saying that everything otaku like and thing is cute is bad.
Moe is... kind of like shoujo Magical Girl culture meets visual novel culture, meets cute culture in Japan, meets lolicon and shotacon, meets all of anime and manga culture, meets Jpop and idol culture, and all sorts of other things. Some parts of it may be bad, but it's very complex and full of good things and bad things. It reflects... maybe the word is trends? Like trends in Japanese... um.. "nerd" cultures.. that instead of escaping from the scariness of work life and bad things about adulthood, to adventure, to cuteness and harmony.
Moe is a trend of escaping to harmony rather than adventure. And of appreciating a certain kind of femininity that is cute. Like the Hello Kitty kind of cute.
