Incorrect. A small, but vocal minority of people are demanding blocks because they are simply incapable of understanding the wider issue, as you have repeatedly demonstrated. This isn't about blocking pornography at all - this is about politicians pandering to the demands of the easily-swayed voters, i.e. those who generally read the tabloid press. Your assertion that 'those who actively try to get around the filter meaning pornographers should be arrested and jailed' is simply laughable. This proposal isn't about arresting pornographers (definition: those who publish pornography), but trying to put a mechanism in place to censor the Internet. Anyone with any technical knowledge of how the Internet works (which you clearly don't have) would understand that it simply won't work for all of the reasons that I and others have outlined in previous posts.
You also seem to think that those who try to get around the blocks should be jailed - what will this accomplish, exactly? I have run my own DNS for decades, and my company does the same. Do we do this to get around blocks? Absolutely not - we do this because we need to resolve the names of both internal and external machines. Are we trying to get around the blocks? Absolutely not. Are we getting around the blocks? Categorically yes. Under your 'plan', this would be an offence, yet we are merely using one of the many Internet technologies as it is supposed to be used.
And where are the parents in all of this? The sensible parents understand that they need to educate their children in safe Internet use. It really isn't hard - a well brought up child will have no problem in using the Internet within the rules laid down by their parents. Parents have a duty to bring their children up to give them the best start in life, and to ensure that they do so in a safe, loving and caring environment. That environment is the responsibility of the parents, and the parents alone. It is not the responsibility of the government to mandate how they should do it. Perhaps some parents should try engaging with their children once in a while, rather than shouting at them from in front of the television. You'd be surprised what this would accomplish - it might even go some way to reduce youth crime and teenage pregnancies too. Take some responsibility for your children.
By the way, one of the best ways to get people to start doing something is to tell them that it is illegal. Children and adults alike are fascinated by the things that they are not allowed to see - it's simple human nature. There's a strong argument for saying that access should be completely unrestricted - let them see what they want to see - and you'll find that they quickly move on to other things. How many of us can remember trying to see an age-restricted movie at school? How many of us stayed out later than we should? It didn't do anyone any lasting damage, yet some people seem to want to try to block everything. When I was at school, the Anarchist's Cookbook used to circulate on floppy disk - and at that time it was perfectly legal to own a copy. Did any of my schoolfriends turn into terrorists? Absolutely not. They read it, tried out a few things, and moved on. Nowadays we seem to think it acceptable to put people in prison for reading it, and to expel children for conducting science experiments. What a wonderful world we live in.
Oh, and as a UK citizen, I am registered to vote, and have never missed an election. The problem in our democratic system is that there really aren't any viable parties to vote for - they are all offering weak policies to pander to people like you. Ever stop to think why so few people vote in our elections? Perhaps it's because the majority of the population are fed up with the current political offering, and feel that whichever way they vote, they won't be listened to. This government (and previous governments) have repeatedly failed to listen to their electorate - we've seen over a million people march united against the UK going to war in Iraq, yet we went anyway. We've seen significant protests about corporate taxation, MPs expenses etc., yet nothing of substance has been done. Just how exactly is a voter supposed to make a difference in this country? We no longer live in a democracy - we are at the beginning of a new and frightening style of government where the population at large is constantly monitored, privacy does not exist and punishments are severe for people who dare to question those in authority. Neighbourhood spies and vigilante groups? Yep, they're already here. We are living in the beginnings of a Nazi-like state, and history repeatedly tells us that this is not a good idea.
