Well at least we both know what we are talking about ;-)
I remember the emphasis on "just" but at the same time I thought the protest made more sense from a feminzai point of view(get out the 'shackles" of housewifery and such).
I've consulted with my friend who recommended it and watches it religiously, and she says the protest was because the first lady made being a wife and mother sound demeaning. You're right that it doesn't make much sense, but we're dealing with Sorkin's caricatures of conservatives here.
