Nice try.
I know damn well what the historical links of that phrase are, and how it's been used by feminists. I have never heard it or read it anywhere Nazism isn't attached to it.
If I were to use the word "lebensraum" to describe the need for human beings to migrate into space, I doubt I'd escape by coyly claiming I'm just using a "German phrase."
That aside, I'm not looking to lock women back into the kitchen. But I do believe that modern families--at least the intact ones--could learn one or two things about how families are supposed to work from our grandparent's generation.
