There's something behind the decision to choose to lash out at a woman. The answer to how to fix internet trolling is like fixing sexism. How do you do that? I'm of the opinion that discourse helps, that changing people's minds changes people's actions. On a more practical level, I do enjoy sassing back at trolls, because I always win, because my job makes me better at arguing. If I can frustrate or embarrass a troll, then that lodges in that person's brain that trolling me is not a consequence-free hobby.
