I have not experienced many h8ers on Twitter. It’s biggest benefits for me are finding out about new music, and sometimes I hear tech news and particularly news about my beloved Drupal community on Twitter first. I have had personal conversations with friends via Direct Message, although that is not my preferred communication medium.
I have a personal way of dealing with toxic people, online and in person. I disengage with them ASAP. I can leave their world of fear and loathing, but they must go on with their miserable selves.
We can set an example for polite and empowering discourse. As a Jew, I have often communicated with Muslims and Christians (and others) in friendship, noting that we share many common beliefs, with a positive message. I’m not going to change any fundamentalist nihilists’ minds, but each one of us who refuses to descend into the “mosh pit” of hate builds a positive community where h8rs will become the minority.
