Googling "Quiet dignity" "Barbie" does not in fact turn up a new toy line, but rather references to the latest tempest in a teapot among organised science fiction writing/fandom/thing, such as this one, which quotes a rather interesting bit, a part of which is:
She has always been a role model for young girls, and has remained popular with millions of them throughout their entire lives, because she maintained her quiet dignity the way a woman should.
("Role model" is kind of an interesting phrase, isn't it?)
But anyway, the thing that came to my mind when I saw that going around (with its associated "She's a nice girl, she doesn't dress slutty, she doesn't complain to Ken about having things tough, and so on" rhetoric) was that Barbie is quiet because she is made of plastic.
This isn't a far-fetched thing to read when a science fiction writer talks about this kind of thing, it's not like robot housewives aren't a staple in genre and even in the surrounding culture.
A woman should be quiet.
Like an inanimate thing.
A toy, to be specific.
Made out of a manufactured substance.
"The way a woman should."
