People on the net throw around dismissive buzzwords like cult, politically correct, whatever, as a way of knowingly winking at one another, not as a way of increasing understanding, and usually without much understanding of what the buzzword really means. I very much don't want to fall into that pattern. But I do use the word cult, and I use it very advisedly. I wouldn't use it in a diatribe against rightists, but I use it with you as an appropriate scientific category of organizational technique that is being systematically employed to develop the right wing coalition you elucidated. One defining attribute of a cult is that its members share a tightly-bound system of beliefs, one of which beliefs is that outsiders just don't and can't understand.
Outsiders are confused and deluded.
They are missing the liberating true vision that the cult members have been awakened to. Only with fellow members is it possible to talk about how things really are, and what should be happening. That's what Reverend Jim Jones and the Davidian Branch were all about. They were experiments. When the research was done, the evidence was burned.
