My guess is that their interest in her "women's perspective" is sincere and well-intentioned, and in the end, I would be inclined to simply take it at face value and leave it at that. Write the blog entries and let them speak for themselves. Of course, if the club ends up pressing her further for more of a women's perspective, then that would provide an opportunity to clarify what, exactly, they mean by that.

If it were in a different setting--at work, for instance--I'd be more inclined to proactively discuss why such a request could be viewed as offensive, annoying, limiting, etc.
