The Hive image, first proposed by the writer Joseph Sobran, illustrated the key point that liberals and Communists, seemingly distinct, belong to the same Hive. They share the same goals, even if they perform different tasks. The metaphor allows us to speak of their activities as coordinated without having to invoke a conspiracy. The queen bee was the Kremlin, and the worker bees toiled in coordinated fashion to serve the queen without ever taking orders.
Real bees work in that fashion.
They signal openly. They serve the queen. But a careful study of their signaling patterns allowed researchers to decode them. In the same way, liberals and socialists and communists communicate openly. Their claims and arguments fall into a consistent pattern.
