Pretend you're an MP. You, or at least your advisors, know how Christian conservatives "think". They believe in things that make them Christian conservatives, like censoring the web. They'll vote for you if you say that you believe those things.
You also know how hackers think. They believe things which evidence suggests are true. Regardless of what you say, if the government has failed to censor the web for 15 years, hackers won't believe it's going to happen. They'll vote for you based on other things.
You need to maximise votes. The winning strategy is obvious: loudly announce your intention to censor the web, but fail to do it. For bonus points, get some experts to tell the Christians it couldn't be done, so you can't be blamed for failing.
I just love Australian politics.
