Y'know, I had a huge response written, and I was all fired up, because the experience Jones had is functionally identical to the experience of anyone who is not a white man on the internet. She didn't have to feed the trolls - She was a black woman who was in a movie they didn't like on principle alone and that was enough. Whether she fought back or not, the result is the same, so one might as well fight back.
But then I realized - I'm not even sure you really read the article, because you're doing exactly what Serano (and Karl Popper before her, in 1949) argues is the wrong way to treat these people.
I read the article that you posted. I wish that its idea of "just ignore them and they will go away" was a viable strategy that worked, but it's never panned out to be true in any situation I've seen, and Popper, who was writing as a Viennese Jew who was on the ground as the NSDAP was consolidating power, also seems to agree that it doesn't work either. These people aren't just trolls, and they aren't on the internet where one can commit hate speech with impunity.
Serano herself speaks from experience, and I speak from my own. Perhaps you remember Grendel? We tried to ignore him so he would go away, but it wasn't enough. We basically voted, by the use of Hush, mute, and other functions, and made it so that he no longer had a useable platform. We judged that his intolerant speech was not to be allowed in our community. We had to make the site basically unusable for him. There are now new user tools that exist specifically because of his presence here - that's the opposite of "ignoring".
