Does Blue MauMau provide just a cynical illusion of debate?
One of the ways you control what people think is by creating the illusion that there’s a debate going on, but making sure that that debate stays within very narrow margins. Namely, you have to make sure that both sides in the debate accept certain assumptions, and those assumptions turn out to be the propaganda system. As long as everyone accepts the propaganda system, then you can have a debate.
Three or four people talking at each other does not constitute much of a community.
