What kind of progress are you talking about?

As far as I can tell, historically leaving oppressive places has a better track record of success for individuals than fighting or trying to talk and understand.

(Eg think of the people fleeing North Korea, the Soviet Union, East Germany, Nazi Germany, etc.

Similar, you are better of quitting a bad company, than trying to reform.

Or just quitting twitter instead of 'talking' to people there.)

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.
