Having not read the thread except for the OP I think it gets back to the exact same heart of the other question: what is moe?
It's a really really broad word.
But I think culturally, it's become a word for a certain type of femininity. The history of the word seems to come a lot from the "bishoujo" anime and visual novel genres. As well as magical girl shows and things like that. It does have a male gaze, but it isn't always a male gaze.
Moe characters can be subjects just as much as objects. Tomoko Kuroki from It's Not My Fault I'm not Popular is a moe character. And I think you could probably argue there's a lot of male gaze in the show. But she's also a subject and most of the anime is about her personality and her inner thoughts, not her as an object as much as a subject.
She's a moe character, but she's more of a subject than an object. And we often see things through her gaze.
And while a lot of people find "protecting a girl" to be moe, and I think that's a problem. I don't think that's all moe is about. There are plenty of characters who aren't meant to feel that way in anime. There are plenty of anime that aren't moe that have that idea, too. A lot of shounen anime have male characters who say things like "I'll protect you". I've heard people tell me it's a bad gender role in Japan, and not just something that happens in anime. And that protecting and caretaking for a woman is seen as a "masculine" thing in Japan.
So maybe it's more of a bad gender role in Japan than just a moe thing?
Yangire characters are seen as moe. But I don't think they're characterized to make you feel like you want to protect them. Though there were unfortunate times where Gasai Yuno was a damsel in distress. I wish that Mirai Nikki didn't have that.
I think that moe has become a lot of things and connected to a lot of things. But you can still understand it. Popular personality traits and physical traits in the otaku and anime fandom are moe. Some of them are healthy, and some of them promote unfortunate traditional gender roles and female submissiveness.
I don't think there's anything degrading about a woman being yangire, especially if she has more to her character than that. And a lot of moe anime are silly comedy anime where silly archetypes are okay to begin with.
