"BadgersPaws, what is your link in this field, what is your area of expertise?"
I work in the technical side of IT, understand how the internet works, understand network security and have been following the examples of China and Australia's attempts at ISP level filtering for some time.
"I still don't understand why the principle in itself of asking for the ability to control what comes into my home is such a bad idea"
Because:
a) It won't work, the filters will still allow a lot of inappropriate material through.
b) Due to 'a' you will still have to maintain security in your own home.
c) The filters will incorrectly block many legitimate web sites by "accident".
d) The filters will be expensive and those costs will be passed on to home users perhaps pricing people off of the internet.
e) Parents will not be aware of 'a' and will think, incorrectly, that internet security is now dealt with, 'b' will therefore be further from their minds and their children will be in harms way.
The key point is probably 'b', even with the filters in place you will have to maintain your own protection at home, you will not be able to trust the filters.
And if you have to maintain protection at home then why bother funding the creation of an unnecessary filter? People like me will benefit from the cash flooding in our direction but it will be utterly pointless. Why not just spend the money on actually educating people about what their going to have to do anyway?
"I don't buy the 'impossible' argumen"
Go and look at the Chinese example, this is an example that is actually being put forward by the proposers of this scheme as showing how censorship of the internet can be managed.
The Chinese have spent far more time and effort than we could ever afford trying to control the internet at the highest of levels. And it doesn't work. The only way they can even attempt to cope is by blocking vast swathes of the internet that generates content quicker than they can keep up with, so no blogging sites or Wikipedia for example. And even then they've had to push for compulsory software to be installed at the PC level which is an admission that top level filtering is a disaster waiting to happen. The internet was built to survive a nuclear way blowing away vast chunks of it's infrastructure, it can deal with a few religious/political fundamentalists trying to block bits of it.
And that's the Chinese example, which is probably the most successful, and that's a very relative term when it comes to censoring the internet.
The Australian example has been even less successful and is surely closer to what we as a democracy with limited funding and a healthy respect for human rights would be able to achieve.
Filters won't work and won't remove the need for parents to be made more aware of how to protect their children. So why not focus time and money on that latter point and do something that will make a difference rather than just putting endless amounts of cash into the IT industries pocket?
