There is a vicious cycle ongoing - as site becomes more shrill, more Cruzers diminish or stop posting, more Cruzers leave the site completely. And when that happens, when Trumpsters have less and less opposition, they can convince themselves they must be all right, Cruzers all wrong, and they get even more shrill (mostly with themselves).
Lather, Reince (no pun intended), Repeat.
And Free Republic will die, as the vast majority of Trumpeteers will not contribute sufficiently to keep the lights on.
Does anyone seriously think that all those Trumpsters that have signed on since August will remain loyal to FR?
