I don't know the particular "listen to women" trend you're referring to there but, as you say, there is no doubt that women hold diverse and independent views like men do.
So no statement by some or other advocate can legitimately claim to be the viewpoint of all women. Myself, I also wouldn't want that to be a bar that must be cleared to get onto the platform and take the mic.
We can listen even as women debate their own varied viewpoints with other women. And women themselves must call out and challenge the misrepresentations made in their name, it's a responsibility that comes with the mic.
What you said more or less, plus my 2c.
