On a personal level I agree but it's not a moving forward solution to withdraw and stay quiet. I'm talking about the general sense of progress, the one where people are more in balance with other people and that involves understanding eachother and eventually it comes down to talking or some form of communication. Yes, clearly what we're doing at the moment (social media and it's ills) is not only not right but very divisive but that does not meat it's going to be like that forever.
If people move from places that have bad social norms (or bad norms of discussion), like say Twitter, to place that have good norms, like say the Slatestarcodex comments section, the experience of the average person will improve.
The bad places can just quietly whither away when no one goes there anymore.
