A group in this context is a set of persons who share a property, in this case their gender.

As to the larger point you are trying to make, I'm sorry, you didn't manage to make one. It is true that any given person can be simultaneously in a privileged group and an underprivileged group (I'm both a man and a very short person), but this is a rather trivial observation much like saying that it can be both night and that at a particular place on Earth.

We get it, people have different possibilities in different contexts, what a remarkable observation! Now stop trying to restrict the possibilities women have to express their experiences, and dragging out a quote from Emerson about how he really dislikes the poor (which he can well do in the privacy of his own dead head or just generally away from me) does not count as discussion.
