I'm impressed that we managed to turn this into such a debate. I don't think that this needs to be a deep dive into the society of Frost Giants. Clearly, there's some kind of sexist pressure on the Frost Giant that makes her unwilling to be at the front of combat, and while you can argue that it doesn't make much sense, there's a lot that makes little sense about sexism. But that's really besides the point. The joke doesn't need to be examined in some wider cultural context; clearly all it is is a joke about sexism in the real world. And as someone who thought that strip #959 may have been a little awkward, but definitely still enjoyed, this strip really was not that awkward at all.
