Wow, that sucks.
I can totally see how rabid R&M fans did this kind of thing (being one of them, I guess? Minus the harassment part). I mean, maybe part of the reason the kind of rabidly anti-women guys are attracted to a show that (IMO) offers a very "masculine" perspective on life, is the very reason for the ensuing tragedy we see here when the writers try to correct it. I am saying: no, it's too late to cleanly add a more feminine dimension, you already attracted the Gamergate crowd as your core fanbase. It would be like Trump trying to give a speech on why women should have the right to grab men by the dick and shame straight white males, and not expecting to piss off some very scary angry dudes.
I still think it was worth it to add the female writers to the show, and it's pretty sad to see this harassment play out. I see it all the time in the tech media, where a female founder who is attractive is threatened with death and rape for the smallest of perceived shortcomings.
