My line is (and will always be) that hidden censorship is the thin edge of the wedge for greater control, and that a faulty technology easily circumvented is pointless. I also have a large problem with any government of any kind telling me how my family should spend it's time, when there is no externality to the activity. But the argument I had really opened my eyes to how the general public (and thus politicians) see this issue. And because of this, I think the filter is coming whether we like it or not. Because tech-literate educated people make up a fraction of the voting public, I fear this is going to happen.
Oh, and I'm not willing to black out my site. I'd hate to think what it would do to my conversion rate.
