I know it's only a minority of FR guys who take such (obvious) glee in making sweeping generalizations about American women, but why do any do it?
Accusations of glee notwithstanding, there is a culural phenomenon occuring wich is likely to increase, that has a more complicated cause than "jerkwater/insecure/lazy American men want a subservient maid." In speaking of cultural phenomena, it's necessary to make generalizations.
Is it? How so? I would think that with the huge potpourri that is the English language, one could talk about nearly everything without making generalizations.
