The point is that once an author is made aware of a trope which can be off putting to some readers, they can attempt to avoid it in future. Obviously the author doesn't have to, and sometimes this particular trope might be necessary, but I don't think its bad to go "hey, this doesn't work for me for x y and z reasons".

From a story telling point of view, ignoring feminism for a minute, I personally find characters dying "randomly" unsatisfying. Joss Whedon does this occasionally, killing off characters essentially at random, rather than letting said character have a heroic moment then dying. I appreciate that this is deeply realistic, but the story lover in me rebels. This is, of course, a different issue from the one I'm approaching, but I wonder if it isn't adding to some people's reaction.
