Republicans and Democrats do not control the media. Capitalists do, and capitalists also control the Republicans and Democrats. You are confusing state repression under capitalism with fascism itself. Capitalism is a brutal system all on its own, and would prefer to keep the bourgeois democratic shell as it’s the most stable and effective at maintaining their control. Capitalists rip off the mask of bourgeois democracy whenever their rule is in actual danger, regardless of the party in power, regardless of how legal or illegal it is.
