Not to mention, these venues will consider the news to be "ancient history" in a month, leaving nothing but mud stains and hurt feelings (I'm personally tired of being painted as a sexist asshole who "just doesn't get it" because I'm a white male) in its wake. The "discussion" will be over, and nobody will be better off because of it.
They'll certainly do something, but most people who care about the issue won't like what is done. They may:
Become even more hostile about the subject.
Be even less willing to open the ranks to more women.
Double down on "it's someone else's problem".
Worse, people who currently give a shit and act on that may just... stop. "I support their work and I just get attacked for it, why bother?"
Is it worth having allies who hold their support hostage?
