This is not remotely democratic without discovery. E.g. if you start an alt, the original would need to be force to display the alt as an alternative. Otherwise it's too easy to control the narrative and prevent anyone from even finding out about the alternative. Today, the primary sub generally actively bans any mention of alternatives. Also the most obviously named forum will attract the new users simply because of the name.

what about of each breakaway pointed to reach other under an opposing views area, where people can go to read the other side, or the group that's breaking away?
