All revolutions are followed by a "reign of terror" a purge to get rid of the supporters of the previous regime.
In this case it will cut a huge swath through arts and entertainment, media, (Print and TV), the Education system, and the legal profession, there will also be a certain percentage of ordinary people who just HATE the ideas of personal responsibility, rule by law instead of "focus group", and capitalism.

The question is, since we can't just leave them there for the rest of their lives, what to do with them. It's the same question that faced Nazi Germany with the Jews, if we can't get any other countries to take them do we just shoot them ? Try to "reeducate them ? Or just stick them all in Hawaii and set up a naval blockade ?
