England is in the grips of Liberalism and this is just one of the results.
Advanced stage would be when a Blair is gone and a Mugabe takes over. Just a case of moving from "moderate" liberalism to the end product.
This is because Liberalism is social AIDS. Once entrenched, it removes a country's ability to resist more serious social diseases such as despotism.
That was one of the frustrating flaws of V for Vendetta, a flick with some energy but horribly muddled ideology. It portrayed the "sheeple" phenomenon while skipping completely what would have been its logical cause, which is exactly what Dalyrmple describes in this piece. On the other hand, while true that the left-wing social disease will lead to disaster, one possible manifestation of it could be the eventual rise of a Hitler type. I would forgive the movie if it predicted that history, but the film's notion is that modern-day conservatism leads to the portrayed dystopia.
