This could lead me to believe the majority of Australians are as passionate about internet censorship as me and my friends. But then I remember that most of my friends are university educated, left-leaning types who work in journalism or the IT industry.

This same selection bias is at work in the online community, particularly on Twitter. The sort of people who use Twitter, who blog, who read the IT media are precisely the sort of people who would oppose internet censorship.

This has led many people to believe if they make enough noise about it online, the Government will drop the filter. Unfortunately, this greatly overestimates the importance and influence of Twitter and social media generally when it comes to real-world politics.

Even an infinite number of angry posts on Twitter, sarcastic blog posts and articles in the IT press would still have no effect on Government policy. Politicians only care about who can deliver them blocs of votes in important electorates.

Online fame is fleeting, but mine was the top article on ABC's The Drum for a little while

As I argue on ABC’s The Drum blog, so far the Christian lobby – which is for the filter – is doing this a lot better than the disparate anti-filter coalition.

This is not to say the anti-censorship campaign is doomed. However, it needs to focus less on preaching to the choir and more on real-life, professional political lobbying.

It’s a big ask, particularly because many of the anti-censorship groups have little experience in direct political action. But it must be done if we are to convince the Government of the immense folly and dire (supposedly) unintended consequences of its current plans.

New South Wales upper-house member Penny Sharpe railed against the filter in her blog. Yes, she is from the Labor party, but the NSW and federal arms aren’t exactly best buddies right now.

Three younger Liberal parliamentarians – MPs Alex Hawke and Jamie Briggs and Senator Simon Birmingham – have also come out against the filter, although this is mainly confirming their previous positions. Most interestingly, Hawke says he has advised the Christian lobby against the filter proposal, even though he is himself a Christian.

As I mentioned the other day, Senator Kate Lundy has been painfully fence sitting. Despite her well known and vociferous opposition to internet filtering while she was in opposition, Lundy wouldn’t say much at all when I spoke to her. Subsequently she posted a lengthy piece on her blog, the gist of which was that she opposed filtering but it was Labor policy before the election, we voted for them and she can’t speak against party policy.

Although there is still an open question about whether Labor’s pre-election policy made it clear the filter would be mandatory – the language was pretty fluffy.

While these small brushstrokes begin to paint of picture of widespread opposition to the filter, no one seems to have an overall idea of how the anti-censorship movement might achieve its goals. Stay tuned…

“Australia does not have a Bill of Rights which protects free speech at a federal level. We don’t have the protections that they have in every other democratic country.That means Australia might be subject to far more stringent regulations on the internet than would be possible in other democratic countries.”

The academic community is singing from the same hymn sheet on this idea, judging by a report released today from media studies profs Catharine Lumby, Lelia Green and John Hartley. “The proposal would set Australia apart from other Western liberal democracies that have opted for a transparent, voluntary filtering regime,” they said.

They analysed the proposed filtering regime and found it could censor a whole lot more than just kiddie porn, including perfectly legal material.

“The ACMA is blacklisting a significant number of sites that are not illegal content but are considered offensive. While this may be considered acceptable where filtering is opt-in by an end user (or parent for family computers), under a mandatory filtering regime this would result in capturing material that is clearly legal but restricted in availability (off the internet) through classification restrictions.”

Unlike the Liberal Party’s shambolic approach to party unity on the emissions trading scheme, Labor polticos are so far toeing the party line on censorship. Senator Kate Lundy wasn’t saying much today, despite her strong record of criticising internet censorship proposals in the past. Looks like Peter Garrett isn’t the only one to have abandoned his principles once in power.
