Crap, I'm supposed to be asleep, but I disagree with your explanation for "gendered" (ridiculous word) guns. Toy makers make what sells. At ONE DAY boys prefer mechanical toys, girls prefer faces. This is not "patriarchy" (ridiculous word in this context).
(Side note: feminist theorists, use real words! Words are useful if you want to be understood, though perhaps you don't. There's always "feminist linguistics", I suppose.)
And it's not that I haven't heard these arguments. It's that whenever someone runs some sort of experiment against the "feminist theory" story, it loses. This is why I especially like the one day old scenario -- after that, feminist theory becomes unfalsifiable.
Now I'm really going to sleep.
