To pin the term down, we've thought long and hard about the concept of rolling back rights, about what that hate contains, what its roots are and how it spreads. What defines it is the wish that other people should stop existing, that they should no longer be free and inhabit their bodies, and that their identities should be cancelled.
That violence is conveyed through comments, but there are many types. It's part of a very broad continuum ranging from comments on a Facebook page to verbal violence in the street.
