Death of Liberalism, and the rise of Neo-Conservatism
It is easily forgotten that both Stalin and Hitler achieved their totalitarian states with the support (often tacit, but also often active) of a large section of the population. This was achieved in both cases by persuading the population that social chaos can only be avoided by treating certain social, political, ethnic or religious groups as a dangerous threat the average 'hard working, right-minded' member of what is now called the 'silent majority'.
In the UK we are seeing exactly the same propaganda at work. Recent examples of this propaganda include treating Muslims as being prone to 'radicalisation', treating young, black people as all potentially part of an unstoppable 'gang culture', branding young white boys from poor backgrounds as drunken 'yobs', and now by claiming that porn addicts are sexual deviants only one step away from becoming paedophiles or rapists. Using 'protection of society' fear-mongering, the government gains the approval of the fearful and selfish majority of the population, and are therefore given free reign to start oppressing minorities right under the eyes of the very voters whose democratic instincts are supposed to prevent this happening.
Once we have reached this point there is not much to be achieved by any one person sticking their head above the parapet. Macarthyism showed that taking individual direct action against a fear-mongering propaganda machine gets you branded a traitor and ruins your life. Instead, it is necessary to form a social counter-movement that exploits the weaknesses of the authoritarian state - namely, that authoritarian leaders are usually irrational, anti-intellectual, and paranoid of showing any sign of weakness.
If we are to prevent a further slide towards NeoConservative socialism/fascism, then it’s up to intelligent and objective people to ignore the Statist fanboys and pick apart every single stupid rule New Labour introduces. This is happening widely now, and Brown's continued idiocy is currently pointed out on a daily basis (eg, discovering that many of Brown's soon to be closed 'failing' schools actually get good or even excellent ratings from school inspectors, or that Brown wants to lock people up for 42 days to protect us, yet lets his staff break basic rules of information security).
There is now a below-the-radar battle taking place in Britain; Brown has a large segment of 'the masses' on his side when it comes to many policy areas, but the liberals have a growing number of intellectuals (even former New Labour cronies like Lord Goldsmith) on their side. At the moment, the rational people are desperately waiting for Brown to get kicked out at the next election. If he doesn't, the shit is seriously going to hit the fan, and I think we'll start to see the kind of social chaos that Brown thinks he's helping avoid. It won't happen at the level of the typical 'protect society at all costs' electorate, but at the level of the social elite - that is, the civil service, the military elite, the Judiciary, the Eurocrats, academics and scientists, and Company directors. A PM needs their support just as much as he needs that of the voters... unless he truly is the next Hitler, in which case he will simply use a combination of 'loyalist' security forces and malevolent mob rule to overcome anyone who questions his authority.
Fortunately, the state of the economy is really scaring people, and that’s probably enough to over-ride the propaganda machine. Self-interest of the most basic kind (ie, food prices, housing shortage, fuel costs etc) will usually over-ride self-interest on a more abstract level. The next election will be the first true test of democracy this country has seen in a long time - if Brown loses, democracy wins.
