I think for me the bright line is human rights. If there were a more nuanced and deeper understanding of human rights among the people who moderate, say, Facebook pages or Twitter, then there would be a greater understanding of why somebody tweeting at you about your stinky vagina or whatever is in fact a violation of your human rights. That kind of thing is frequently not taken seriously by these platforms as a form of hate speech, so that's where I think the lack of understanding is.
