I have no idea how to solve the monstrous problems related to internet harassment. It is well out of hand, especially as regards women on the internet (see: Anita Sarkeesian).
I think a discourse definitely needs to happen. But maybe the only solution lies in the education and mental health systems. But again, I don't know. Wish I knew, wish I could do more to help. Wish my gender weren't responsible for the vast majority of the harassment, violence, and threats of violence.
Best of luck. Please keep posting about this topic and looking for and experimenting with solutions. Progress can only be made by people like you taking the time to try to do something about an urgent problem like this.
