Emotional Attachments can be formed in an instant though and having them form very quickly isn't something that's uncommon. It could be there beauty attracts people and almost instantly they want to protect them. For an example; You see a gorgeous horse and you'd hate to see something bad happen to it. So, if it did run into trouble you'd run in to try to protect it.
And even then I really don't think we can use that or any fan translation as a basis for any argument unless we get official word from SE saying "this is what he said" because we've gotten three very different translations for it and don't really have any way of saying for sure which is right unless we get actual official, and in english, confirmation. The only actual confirmation we definitely have from SE in regards to the design process of Au Ra is that they are "elegant and mysterious"(x).
Yoshi-P probably (if that was what he was saying) wasn't defending the design to you, me, or anyone one the forums (maybe...) but to the plethora of people who have called him and the devs everything but their names in regards to the female Au Ra. Which, honestly, was a good chance probably mostly coming from Tumblr.
